Question

if the gravitational field strength at a height h above the earth of radius R is same as at a depth of R/2 , then h has value ? options are A) R and B) R/2 and C) ( √2- 1) R and D) √2R. please copy paste and if you may write down answer and forward the image written answer try to pick any option as asked in question thankyou​

Answer 1

Answer:

R/4

Explanation:

g(1-D/R) = g(1-2h/R)

D = 2h (D = R/2)

h= R/4
