Question

derive the equation for by which is universal law of gravitation constant capital G

Answer 1

the force of interaction of stationary point charge at any point is directly proportional to the charges and inversely proportional to distance between two charges
F proportional q1q2
F proportional 1/rsqure
F proportional q1q2/rsqure
F = Gq1q2/rsqure
G = gravitational constant

Answer 2

proved... I hope it help you
