Question

Two point masses m and 2m are kept at points A and B as shown. E represents magnitude of gravitational field strength and V the gravitational potential. As we move from A to B 

(a) E will first decrease then increases 

(b) E will first increase then decrease 

(c) V will first decrease then increase

(d) V will first increase then decrease

Answer 1

Correct option (a) E will first decrease then increases and (d) V will first increase then decrease

Explanation :

So, field first decreases and then increases.

So, V first increase and then decreases.
