Question

Two charges of 

q1 = 1.3 µC and  q2 = −2.5 µC are d = 0.46 m apart at two vertices of an equilateral triangle as in the figure below.
 
(a) What is the electric potential due to the 1.3-µC charge at the third vertex, point P?
 V

(b) What is the electric potential due to the 
−2.5-µC charge at P?
 V

(c) Find the total electric potential at P.
 V

(d) What is the work required to move a 4.0-µC charge from infinity to P?
The image illustrates a geometrical arrangement involving two point charges and a point labeled "P". 

- There are two charges shown: \( q_1 \) and \( q_2 \).
  - \( q_1 \) is a positive charge, represented by a red sphere with a plus sign.
  - \( q_2 \) is a negative charge, represented by a blue sphere with a minus sign.

- These charges are placed at either end of a horizontal line segment. The distance between \( q_1 \) and \( q_2 \) is labeled as \( d \).

- Above the midpoint of the line segment connecting \( q_1 \) and \( q_2 \), there is a point labeled "P".
  - The point \( P \) is equidistant from both charges, and the distance from each charge to point \( P \) is also labeled \( d \), forming an equilateral triangle.

This configuration is useful in problems involving electric fields or potentials, where the point \( P \) is often a location of interest for calculating these quantities.
