Two circular plates, each with a radius of 9.22 cm, have equal and opposite charges of magnitude 0.652 pC. Calculate the electric field between the two plates. Assume that the separation distance is small in comparison to the diameter of the plates. electric field: N/C The plates are slowly pulled apart, doubling the separation distance. Again, assume the separation distance remains small in comparison to the diameter of the plates. What changes occur with the electric field between the plates? The electric field decreases by a factor of 2. O The electric field decreases by a factor of 4. O The electric field increases by a factor of 4. O The electric field increases by a factor of 2. O The electric field stays the same.A small 2.65 g plastic ball that has a charge q = 1.35 C is suspended by a string that has a length L = 1.00 m in a uniform electric field, as shown in the figure. - - - If the ball is in equilibrium when the string makes a 0 = 9.80 angle with the vertical, what is the electric field strength E? L E E = N/C - -A charged box (m = 455 g, q = +2.50 pC) is placed on a frictionless incline plane. Another charged box (Q = +75.0 pC) is xed in place at the bottom of the incline. If the inclined plane makes an angle 0 of 350 with the horizontal, what is the magnitude of the acceleration of the box when it is 43.0 cm from the bottom of the incline? What is the direction of the acceleration of the box? 0 up the ramp 0 down the ramp 0 neither
