Question

Question 8: The potential at point A is 25 V, and the potential at point B, which is 10 cm away from point A, is 3 V. What is the direction of the electrostatic force vector on a point charge Q = -2 nC placed at the midpoint C?

QUESTION 8 The potential at the point A is 25 V, and the potential at the point B, which is 10 cm away from point A, is 3 V. what is the direction of the electrostatic force vector on a point charge Q-2 nC placed at the midpoint C? o downward o to the right O upward o to the left

Explanation / Answer

electric field is directed from high potential to low potential

E is from A to B

negative charge moves from low potential to high potential

electic force on negative is from B to A

to the left

==================

Pmax = I^2*RL

I = V/(R0+RL)

Pmax = (V/(R0+RL))^2*RL
