Question

what will be the effect on the acceleration due to gravity and universal constant of gravitation if the mass of the earth become 4 time and radius remains the same?​

Answer 1

Answer:

as we know that g =G Me/r²

the value of G = 6.67×10^-11 Nm²

Explanation:

now if we put Me = 4Me then

g = 6.67×10^-11Nm² 4(6×10^²⁴m)/(6.4×10^6m)²

g = 3.9 m/s²
