Question

Three charges each of magnitude q are placed at the
corners of an equilateral triangle, the electrostatic
force on the charge placed at the centre is (each side of
triangle is L)
A
FA
B
(a) Zero
(b)
19
4me,
14
12102, L
(c)
1 30
4,
(d)​

Answer 1

Answer:

a

Explanation:

The vector sum of all the forces would be zero

as distance from the centre is l/root3

so magnitude of all the forces be same

angle between each force vector is 120
