A suitable unit for gravitational constant

Your Ultimate Guide to JEE & NEET Question Solutions

A suitable unit for gravitational constant is

$kg{\rm{ - }}\,m\;{\sec ^{ - 1}}$

$N\;{m^{ - 1}}\sec $

$N\,\,{m^2}\,k{g^{ - 2}}$

$kg\,m\,{\sec ^{ - 1}}$

A suitable unit for gravitational constant is

$F = \frac{{G{m_1}{m_2}}}{{{d^2}}};$

$\therefore $ $G = \frac{{F{d^2}}}{{{m_1}{m_2}}} = N{m^2}/k{g^2}$
