1.Two bodies of masses 4m4m4m and 9m9m9m are separated by a distance rrr. The gravitational potential at a point on the line joining them where the gravitational field becomes zero is:a.−25Gmr-\frac{25Gm}{r}−r25Gmb.−4Gmr-\frac{4Gm}{r}−r4Gmc.−9Gmr-\frac{9Gm}{r}−r9Gmd.−13Gmr-\frac{13Gm}{r}−r13GmLogin to continueOnly logged in users canattempt or see the solution.
