The gravitational field in a region is given by `vec(E) = (4hat(i) + 3hat(j)) N//Kg`. The gravitational potential at the points (3m, 0) and (0, 4m). If the potential at the origin is taken to be zero.

Text Solution

Verified by Experts

`vec(V) = -(vec(E).vec(r))`
At (3m, 0) `vec(V) = -(4hat(i) + 3hat(j)) .(3hat(i)) = -12J//kg`
At (0, 4m) `vec(V) = -(4hat(i) + 3hat(j)) .(4hat(j)) = -12J//Kg`
