NEET Solved Paper 2014 Question 12

Question: Dependence of intensity of gravitational field (E) of earth with distance (r) from centre of earth is correctly represented by [AIPMT 2014]

Options:

A)

B)

C)

D)

Show Answer

Answer:

Correct Answer: B

Solution:

For a point inside the earth r < R $E=\frac{GM}{R^3}r$

At a centre, r = 0, E = 0 For a point outside earth r > R, $E=\frac{GM}{R^2}$

On the surface of earth r = R,$E=\frac{GM}{R^2}$
