1. Motion of a ged particle: An electron is ini y moving to the right when it enters a uniform electric field directed upwards. WIIich trajectory shown below will the electron follow? A) trajectory W B) trajectory X C) trajectory Y D) trajectory Z 2. In the figure, a ring 0.71 m in radius carries a charge of + 580 nC uniformly distributed over it. A point charge Q is placed at the center of the ring. The electric field is equal to zero at field point P, which is on the axis ofthe ring, and 0.73 m from its center. (Eo = 8.85 x 10-12 C2/N m ) The point charge Q is closest to A) -210. B) -300. C) -420. D) 210. E) 300.
