Q. Positive charge Q is distributed uniformly over a circular ring of radius R. A particle having a mass m and a negative charge q, is placed on its axis at a distance x from the centre. Find the force on the particle. Assuming x << R, find the time period of oscillation of the particle if it is released from there.

Positive charge Q is distributed uniformly over a ircular ring of radius R. A particle having having a mass ma and a negative charge q, is placed on its axis at a distanc ex from the centre. Find the force on the particle. Assuming x<< R, Find the time period of oscillation of the particle if it is released from there.

A thin fixed ring of radius $1 m$ has a positive charge $1 \times 10^{- 5} C$ uniformly distributed over it. A particle of mass $0.9 g m$ having a negative charge of $1 \times 10^{- 6} C$ is placed on the axis at a distance of $1 c m$ from the centre of the ring. Assuming that the oscillations has small amplitude, the time period of oscillations is:

Q. A thin fixed ring of radius 1m has a positive charge

1 \times 10^{- 5}

C uniformly distributed over it. A particle of mass 0.9 g and having a negative charge of

1 \times 10^{-} 6

C is placed on the axis at a distance of 1 cm from the centre of the ring. Calculate the time period of oscillations.

A ring of radius 100 cm has a uniformly distributed charge Q and uniformly distributed mass m. On the axis a point charge –Q of mass 2m is placed at a distance 3 cm form its centre. Both are released from rest. Assuming only electric interaction between the ring and particle, find the amplitude (in cm) of SHM of particle.___
