Question

The weight of a body on the earth is 392 N. What will be the weight of this body on a planet whose mass is double that of the earth and and radius is four times that of the earth.

Answer 1

weight and mass from pound to newton earth Conversion Results: Calculate newtons earth in weight and mass per 1 pound unit. ... Conversion for how many newtons earth, N, of weight and mass units, are contained in a pound, lb - lbs?

Answer 2

Answer:

49N

Explanation:

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 =

now putting value,

if that planets Mars is 2 times the earth then the gravitational force will be 392 × 2.

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

392 × 2 / 4².

that will be equal to 49 Newtons.
