Question

What is the force of gravitation if 2 objects of mass 2kg and 4kg are place 2m apart

Answer 1

Answer:

13.34× 10^-11 newton is the answer

Answer 2

F = Gm1m2/r^2

Where F is the attractive force between 2 masses, m1 and m2, r is the distance between the centres of the masses and G is the universal gravitation constant, which is 6.674x10^-11 Nm^2/kg^2

IF, however, one mass is much greater than the other, we can write

g = GM/r^2 where M is the larger mass (and we call g “gravity”, or more properly “the acceleration due to gravity”; g has units of m/s^2)

Now, if m1 = 1kg, m2 = 2kg and r = 1m, then

F = (6.674x10^-11)(1)(2)/1^2 = 1.3348x10^-10N
