97 At a distance from a uniformly charged long wire a charged particle is thrown radially outward with a velocity u in the direction perpendicular to the wire When the particle reaches a distance 2 from the wire its speed is found to be 2 u The magnitude of the velocity when it is a distance 4 away from the wire is ignore gravity a 3 u c 2 2 u b 2u d 4u
