According to Newton's law of gravitation , the force F between tow bodies of masses `m_1` and `m_2` placed at a distance of 'r' form each other is given as
`F = G xx (m_(1)xx m_(2))/r_(2)` , where G is the universal gravitional constant. Find the units of G in both C.G.S. and S.I. system.

Text Solution

Verified by Experts

Express .G. in terms of F, 1, `m_1` and `m_2` . If C.G.S. unit of F, r, and mare dynes, cm and g, respectively, then on substituting these values, is it possible to obtain C.G.S. unit of .G.? If S.I. units of F, r and m are N, m and kg, respectively, then on substituting these values, is it possible to obtain S.I. unit of .G.?
