Solution

The correct options are
A 2 big spheres
B a rod
C 2 small spheres
Gravitational constant is experimentally determined by the Cavendish experiment. It uses a torsional balance, 2 big spheres, 2 small spheres and a rod. The faint attraction between balls placed alongside the beam is detectable by the deflection it causes. It uses the concept of Force-Torque equilibrium.

. In this experiment, two hard spheres, each of mass

M

are brought nearer the small suspended sphere for producing torsion, the deflection in the suspended rod is
