A parallel plate capacitor is made using two square plates, 6.38 centimeter on a side, spaced 0.380 centimeter apart. An electron is sent through the plates with speed 1.74 x 106 m/s and is deflected 30o. Obtain the charge on each plate.
An 8g bullet is fired at a speed of 216 m/s into a 190 g block that is initially at rest at the edge of a table of 1m height. The bullet fully embeds itself in the block before the bullet-block system launches off the table. How far in the x-direc..
