Four equal +6.00-μc point charges are placed at the corners of a square 2.00 m on each side. (k = 1/4π ε0= 8.99 × 109 n · m2/c2) (a) what is the electric potential (relative to infinity) due to these charges at the center of this square? 153 kv previous answers correct part b (b) what is the magnitude of the electric field due to these charges at the center of the square? n/c

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
