Supposing Newton's law of gravitational ...

Supposing Newton's law of gravitational for gravitation fores `vecF_1` and `vecF_2` between two masses `m_1` and `m_2` at positions `vecr_1` and `vecr_2` read `vecF_1 = - vecF_2 = - (vecr_12)/(r_12^3) GM_0^1((m_1m_2)/(m_0^2))^n` where `M_0` is a constant of dimension of mass. `vecr_12 = vecr_1 - vecr_2` and n is a number. In such a case

A

the acceleration due to gravity on earth will be different for different objects.

B

noene of three laws of Kepler will be valid.

C

only the thrid law will become invalid.

D

for n negative, an object lighter than water will sink in water.
