Question

mass oi 2. Find the acceleration due to gravity at a height equal to half the radius of the earth if g= 9.8 ms²​

Answer 1

Answer:

Let the radius of earth from surface of earth is R and the height equal to half the radius of earth from surface of earth is h.

The acceleration on the surface of earth due to gravity is given as,

g=R2GM

The acceleration at a height due to gravity is given as,

g′=h2GM

=(2R)2GM

=4g

=4×10

=40m/s2

Thus, the value of acceleration at a height due to gravity is 40m/s2.
