What would happen if the earth was half its size?
If earth shrinks to half, then it can increase gravity on surface of earth. Hence, the weight of every person on earth will increase. Hence, its clear from this expression that gravity will increase and our weight too.
At what height value of G becomes half?
If we use 6,371 km as Earth’s radius, the distance above the surface where gravitational acceleration is halved would be 2,639 km.
What happens if earth shrinks?
If the radius of earth shrinks by 1.5\% (mass remaining same), then the value of gravitational acceleration changes by. A. The earth becomes more compact that indicates that the gravitational force on the test mass will increase, and hence the acceleration due to gravity will also change.
What would happen to the graph if the earth shrinks to half of its radius?
Hence, the correct answer is that If the radius of the earth is reduced to half of its present value, with no change in the mass, the acceleration due to gravity will become Four times to that of the original value which is option B.
How will the value of g be affected if the rotation of the earth stops?
The value of acceleration due to gravity at a place (at given latitude) is affected due to its rotational motion. The effect of rotation of the earth on acceleration due to gravity is to decrease its value. Therefore if the earth stops rotating, the value of g will increase.
What will be the value of G at the Centre of the earth *?
Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2….The Value of g Depends on Location.
| Location | Distance from Earth’s center (m) | Value of g (m/s2) |
|---|---|---|
| Earth’s surface | 6.38 x 106 m | 9.8 |
| 1000 km above surface | 7.38 x 106 m | 7.33 |
When the earth shrinks without reducing its mass What change will be there in the duration of a day and why?
If earth shrink (without change in mass) to half it\’s present size. Length of the day would become `6` hours. As size of earth changes its moment of inertia changes.
What would happen if we halve the radius of the Earth?
Nothing, as we’d destroy the Earth. And Everybody Dies ( tm). Volume is proportional to radius cubed. To halve the radius and keep the mass the same, the volume has fallen by 7/8, so we need to increase the density by a factor of 8. This is more than twice the density of any known element.
What is the value of G at a particular point?
The value of g at a particular point is 10 m s^-2. Suppose the earth shrinks uniformly to half of its present size without losing any mass. The value of g at the same point (assuming that the distance of the point from the centre of the earth does not change) will now be. 11th
What would happen to Earth if it was sucked into a black hole?
An Earth mass black hole would have an event horizon of about 1.7 centimeters. This would either devour the Earth, or the energy released by materiel falling into it would destroy the Earth in a blast of radioactivity ( again) As Earth no longer exists, the object will have no weight, and has probably been destroyed as well.
What happens to the weight of the body when the radius is halved?
Only , the weight of the body becomes four (4)times the initial weight when the radius of the earth is halved and its mass is kept constant due to the increase in acceleration due to gravity (g) of the earth. Early symptoms of spinal muscular atrophy may surprise you. Signs of spinal muscular atrophy can be easily ignored.
