Two parallel plates are arranged horizontally and held at a potential difference of 10 kv, and they are separated by a distance of 7 cm. a proton enters the region halfway between the plates traveling parallel to the plates at a velocity of 3.2x107 m/s
(a)what is the electric field between these plates?
(b)what is the force this electric field places on the proton?
(c)what horizontal distance does the proton travel before striking one of the plates?

The earth is constantly spinning on its axis, like you might spin a basketball on your finger. it is this spinning of the earth that causes

What is the electric force acting between two charges of -0.0045 c and -0.0025 c that are 0.0060 m apart? use fe=kq1q2/r^2 and k = 9.00 x 10^9 n*m^2/c^2 a. 1.7 x 10^7 n b. -1.7 x 10^7 n c. -2.8 x 10^9 n d. 2.8 x 10^9 n

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
