Question

Calculate the force of gravitation between a man weighing 60 kg and a boy weighing 40 kg standing 2m apart. (Take G = 6.67 x 10-11 Nm2/ Kg2)

Answer 1

Answer:

F=4*10^(-8)N

Explanation:

as per newton's law of gravitation,

F=Gm1m2/r²

F=6.67*10^(-11)*60*40/4

F=4*10^(-8)N

Answer 2

Answer:

40.02×10^(-9) N

Explanation:

we know that

F = G(m1 × m2)/r²

we have

F = {6.67×10^(-11)× 60×40}÷2²

F = 6.67×10^(-11)×6×10²

F = 6.67×6×10^(-9)

we get the ans
