Question

The value of ‘g’ on earth’s surface is 9.8m/s2

. Suppose the earth suddenly
shrinks to one-third of its present size without losing any mass. What is the value
of ‘g’ on the surface of the shrunken earth?

Answer 1

Answer:

Acceleration of gravitation, a=

R

2

GM

Where,

M is mass of earth and R is separation between both masses.

If volume is reduce, keeping mass and separation between them same then.

From the formula it is clear that acceleration of gravity will remain constant.

Hence, value of gwill be 9.8ms

−2

Answer 2

Answer:

9.8ms^-2

hope it helped u out

pls mark me as brainliest
