The force of gravitation between a stone weighing P and a man weighing Q is R. If the distance between their centres is S, which value for P, Q, R and S is correct? A) P: 80 kg, Q: 90 kg, R: 1.88 x 10 -8 N, S: 4 m
B) P: 50 kg, Q:90 kg, R: 1.88 x 10-8 N,S:4m C) P: 50 kg, Q: 90 kg,R: 1.88 x 10-8 N,S:2 m
D) P: 50 kg, Q:90 kg, R: 3.88 × 10-N,S:4 m

Answer:
Step-by-step explanation:
The correct answer is B) P: 50 kg, Q: 90 kg, R: 1.88 x 10^-8 N, S: 4 m. The formula for the force of gravitation between two masses P and Q, separated by a distance S, is R = G (PQ)/S^2, where G is the gravitational constant.
