A mass m carrying a charge q si suspended form a string and placed in a uniform horizontal electric field of intensity E .The angel made by the string with the vertical in the equilibrium position is

A pendulum bob of mass m , carrying a charge q is at rest with its string making an angle theta with the vertical in a uniform horizontal electric field E. the tension in the string is

A small charged particle of mass m and charge q is suspended by an insulated thread in front of a very large conducting charged sheet of uniform surface density of charge sigma . The angle made by the thread with the vertical in equilibrium is

A pendulum bob of mass m charge q is at rest with its string making an angle theta with the vertical in a uniform horizontal electric field E. The tension in the string in

A pendulum bob of mass m charge q is at rest with its string making an angle theta with the vertical in a uniform horizontal electric field E. The tension in the string in

A positively charged particle of charge q and mass m is suspended from a point by a string of length l. In the space a uniform horizontal electric field E exists . The particle is drawn aside so that it is projected horizontally with velocity v such that the particle starts to move along a circle with same constant speed v. Find the speed v.
