Question

1. 1A The figure at the right shows portions of two infinitely large, parallel, non conducting sheets, each with a fixed uniform charge. The surface charge densities are or 6 uc/m2 and o2 2 HC/m C Inn (7.5 points) Three points P, S, and Uare located at the vertices of a equilateral .A triangle of side 10 mm. Rank the points according to the electrical potential at those positions respectively, greatest first. (Circle your ans a) U, P, S b) P, U, S c) P, S, U e) NA d) U, S, P (7.5 points) Three electrons are located at the vertices of a equilateral triangle PSU of side 10 mm, Rank the electrons according to their electrical potentialenergy, greatest first. (circle your answer). b) P, U,S a) U, P, S S, U e) NA d) U, S, P

Explanation / Answer

1) c) P,S,U

because left plate is at higher potential and right plate is lower potential.

so, as we move from left to right potential decreases gradually.

2) a) U,P,S

beacuse potential energy = q*V

but eletron has negatice charge.so, If potential is more at a point electron has less potential enrgy at that point.
