Question

Gravitational force of attraction "F" exists between two point masses A and B when a fixed distance separates them. After mass A is tripled and mass B is halved, the gravitational attraction between the two masses is

Answer 1

1.5 F

Step-by-step explanation:

F = G m1 m2/ r^2

new force F' = G × 3m1 × 0.5 m2 / r^2

F' = 1.5 ×G m1 m2/ r^2

F' = 1.5 F
