Determine gravitational potential from gravitational potential energy. |
|
Answer» <P> Solution :(i) Consider two masses `m_(1)` and `m_(2)` separeted by a distance R which has gravitational potential energy U(r)/(ii) The gravitational potential due to mass `m_(1)` at a POINT P which is at a distance r from `m_(1)` is OBTAINED by making `m_(2)` equal to unity `(m_(2) = 1 kg)` (iii) THUS the gravitational potential V(r) due to mass m = 1 at a distance r is `V (r) = (Gm_1)/(r)`. |
