A charged particle of mass 0.003 g is held stationary in space by placing it in a downward direction of electric field of 6xx10^(4)NC^(-1) . Then, the magnitude of charge is

A cylinder of large length carries a charge of 2xx10^(-8)Cm^(-1) find the electric field at a distance of 0.2 m from it.

A particle of mass m = 0.1 kg and having positive charge q = 75 mu C is suspended from a point by a thread of length l = 10 cm . In the space, a uniform horizontal electric field E = 10^4 NC^-1 exists. The particle is drawn aside so that the thread becomes vertical and then it is projected horizontally with velocity v such that the particle starts to move along a circle with the same constant speed V. Calculate the radius of the circle and speed v(g = 10 ms^-2) .
