Two small spheres, each of mass 0.1 gm and carrying same charge 10 -9 C are suspended by threads of equal length from the same point. If the distance between the centres of the sphere is 3 cm, then find out the angle made by the thread with the vertical. (g = 10 m/s 2 ) & tan –1 
= 0.6º
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(tan –1 (1/100) = 0.6º)
Sol. (i)
From the given diagram,
tan θ = 
= 
= 
∴ θ = tan –1 
= 0.6º
