A particle of mass m=0.1kg and having positive charge q=75μC is suspended from a point by a thread of length l=10cm. In the space, a uniform horizontal electric field E=104NC−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).
