Question

The weight of a body on the surface of the earth is 294 N. What will be the

weight of this body on a planet whose mass is double that of the earth and radius

is four times that of the earth.​

Answer 1

Answer:

we know that weight of an body = product of its mass and acceleration due to gravity.

and we also know that weight of an body is the force of attraction by which the earth attract that body towards its centre. according to universal law of gravitation given by newton =

force = 6.7 x 10-11

now putting value,

massixmass2 distance

mass x mass 2 if that planets Mars is 2 times the earth distance then the gravitational force will be 392

392 = 6.7 x 10-11

2.

and if the radius of that planet is 4 times the earth then the gravitational force will

be

392 x 2/ 4?.

392 x 2 16

that will be equal to 49 Newtons.

Answer 2

Answer:

Assertion

The weight of an object changes from place to place but not mass.

Reason

The weight of the object is independent of the value of g
