Question
In a certain region of space gravitational field is given by I = – (K/r). Taking the reference point to be at r = r_{0} with V = V_{0}, find the potential.




None of these
easy
Solution
We know that intensity is negative gradient of potential, i.e., I = – (dV/dr) and as here , so
Note: In this problem we cannot assume potential to be zero at r = 0 or r= ∞.
