Question

if gravitational field is given by E = Gm where G stands for gravitational constant, m stands for mass
and r stands for distance, then dimensions of E are ( Given dimensions of G=(M-*LPT-21)
​

Answer 1

Answer:

[ L T⁻² ]

Explanation:

Seems like the correct equation is E = Gm/r².

⇒ E = [G] [m] / [r]²

       = [M⁻¹ L³ T⁻² ] [ M ] / [L²]

       = [M⁻¹ L³ T⁻² M L⁻² ]

       = [M⁻¹⁺¹ L³⁻² T⁻² ]

        = [ L T⁻² ]
