Question

How to find electric potential at the center of a square?

Answer 1

For example:-

a) Calculate the electric potential at the center of the square described as follows: Four charges are placed at the corners of a 20 cm square. The particles are as follows: 10 muC at (0,0);...

a) Calculate the electric potential at the center of the square described as follows: Four charges are placed at the corners of a 20 cm square. The particles are as follows: 10 muC at (0,0); -5 muC at (20,0); -15 muC at (20, 20); and 20 muC at (0, 20).

b) What is the electric potential energy of the above configuration in part a?

Electric potential due to a system of charges placed in air is given by

V = V_1 + V_2 + V_3 + ... + V_n

= 1/(4piepsi_0)sum_(i=1)^nq_i/r_i

= 1/(4piepsi_0)(q_1/r_1 + q_2/r_2 + q_3/r_3 + ... +q_n/r_n)

Here, four charges have been placed at the corners of a 20 cm square. The electric potential at the center of the square has to be calculated.

Hope this helps you.....
