An object has a weight of 100 n on the surface of the earth. if the object is moved to 2re above the surface of the earth, its weight is 25.0 n. 11.0 n. 0 n. 100 n.

Weight of the object is defined as

here

m = mass of object

g = acceleration due to gravity

now at the surface of earth

so given that

now when it is moved to distance 2Re from the surface so its distance from the center of earth will be given as Re + 2Re = 3Re

so acceleration due to gravity will be given as

so now weight is given as

so now weight will be 11 N
