An electron is released from rest on the axis of a uniform positively charged ring, 0.100 m from the ring's center. If the linear charge density of the ring is +0.149 C/m and the radius of the ring is 0.200 m, how fast will the electron be moving when it reaches the center of...

A square surface measures 4.4 mm on each side. It is immersed in a uniform electric field with magnitude E = 2100 N/C and with field lines at an angle of 35 with a normal to the surface. Take that normal to be "outward," as though the surface were one face of a box. Calculate...
