Question

ABC is an isosceles right angled triangle having right angle at ‘A’. Three equal charges of +2 C are
placed at A, B and C respectively. P, Q and R are the midpoints of AB, BC and CA respectively
(AB = AC = 2 cm).
Find the electric potential V at the circumcentre of the ABC.
If the charges at A, B and C are now removed, what equally distributed
charges are to be placed at midpoints P, Q and R to produce the same
amount of electric potential ‘V’ at the circumcentre of ABC?

Answer 1

placed at A, B and C respectively. P, Q and R are the midpoints of AB, BC and CA respectively

(AB = AC = 2 cm).

Find the electric potential V at the circumcentre of the ABC.

If the charges at A, B and C are now removed, what equally distributed

charges are to be placed at midpoints P, Q and R to produce the same

amount of electric potential ‘V’ at the circumcentre of ABC
