Weight of a person at a height of 2R from the centre of the earth, where R is the radius of the earth- (1) remains same (2) becomes half (3) becomes twice (4) becomes one-fourth

Description : Weight of a person at a height of 2R from the centre of the earth, where R is the radius of the earth- (1) remains same (2) becomes half (3) becomes twice (4) becomes one-fourth

Last Answer : (4) becomes one-fourth Explanation: The gravitational force is proportional to 1/R2, where R is the distance from the centre of the Earth. So at a height of 2R from the centre of the earth, the corresponding weight would be one-fourth of the original weight.

If the mass of an object is doubled and the mass of object B is halved, what will be the difference in the weight of the two objects on earth ?

Description : If the mass of an object is doubled and the mass of object B is halved, what will be the difference in the weight of the two objects on earth ?

Last Answer : Weight depends a lot on mass. The mass of the two objects does not hold 2 . The previous weight of A is w = 2 * 9.8 = 19.6 N. If I double, mass = ( 2 * 2) = 4 . Therefore w '= 4 * 9.8 = 39.2 N. . Again b's w "= 2 * 9.8 = 19.6 N .. And halving the mass = 1 .

How do I find the distance an object is from the earth with only it's mass and weight in it's current position?

Description : How do I find the distance an object is from the earth with only it's mass and weight in it's current position?
