Question

The value of g at a particular point is 9.8 m/s2. Suppose the earth suddenly shrinks
uniformly to half its present size without losing any mass. The value of get the same
point (assuming that the distance of the point from the center of earth does not
change) will now be:
a) 9.8 m/s?
b) 19.6 m/s2
c) 4.9m/s2
d) 39.2m/s2​

Answer 1

Answer:

i think it is d 38.2 m/s२

Answer 2

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
