As shown in the figure, a configuration of two equal point charges (q Q = +2 µC) is placed on an inclined plane. Mass of each point charge is 20 g. Assume that there is no friction between charge and plane. For the system of two point charges to be in equilibrium (at rest) the height h = x x 10 -3 m. The value of x is (Take 
= 9 x 10 9 N m 2 C -2 , g = 10 m s -2 )
Text Solution
Verified by ExpertsThe correct answer is:
300
(300)
For the condition of equilibrium, the Coulomb force is equal to mg sin 
. Hence,
