A solid plastic ball has a radius of 6.0 cm and has a charge of +3.o nC ( in nano-Coulombs) that is uniformly distributed throughout its volume. Imagine there is a proton being held 1.5 cm away from the surface of the solid plastic ball, and then the proton is released. The proton will accelerate away from the ball, as we know, due to the repulsive electric force. Assuming the ball doesn't move, how fast is the proton moving when it is 5.5 cm away from the surface of the ball?
Calculate the strength and direction of the electric field, E, due to point charge of 2.7 nC at a distance 5.6 mm from the charge. For the direction, consider the line joining the point charge and point at the distance 2.4mm. The direction on this line away from the charge is positive and the direction towards the charge is negative. What force does the electric field found in the previous example exert on a point charge of −2.3·10^-8 C?
I would like to have a factual solution and answer here please? thank you. Two point charges are placed on the x-axis as follows: Charge ?1 = +4.00 nC is located at ? = 0.200 m, and charge ?2 = +5.00 nC is at ? =−0.300 m. What are the magnitude and direction of the total force exerted by these two charges on a negative point charge Charge ?3 = −6.00 nC that is placed at the origin?
