Two bodies of masses 3.0 kg and 2.0 kg are separated by a distance of 50 cm. Calculate the force of attraction between them. [G = 6.67 x 10−11 Nm2 kg2]
1.6 x 10−9N
1.3 x 103N
2.3 x 103N
5.0x 103N
Correct answer is A
Using the formula
F = Gm1m2r2
= 6.67×10−11×3.0×2.0(50)2
= 40.02×10−112500
= 1.6 x 10−9N
