Question

The force of attraction between two masses each of 1 kg kept at a separation of 1 m is — (a) 9.8 N (b) 6.7 N (c) 980 N (d) 6.7 × 10^-11 N

Answer

6.7 × 10^-11 N

Reason

Radius (r) = 1 m

Masses = 1 kg each

G = 6.7 × 10 ^-11 N m ² kg^-2

F = $6.7×10^{-11}×1×1\over 1^2$

= 6.7×10^-11 N

Hence, the force of attraction = 6.7 × 10^-11 N
