Question

11. Three charges each q are kept at 3 corners of a
square as shown in figure and
Electric field at the centre is
(1) Brez towards D
(2) de
towards B
19
(3) 4
towards D
(4) 4
towards B​

Answer 1

Answer:

I don't no sorry.........

Answer 2

The net electric field at the centre of the square will be in the direction towards D.

• The electric field at the centre of the square due to the two opposite diagonal point charges at A and C will be equal in magnitude an opposite in direction and hence will cancel out each other.
• Therefore, the net electric field at the centre of the square will be only due to the charge placed at B, which will be in a direction away from B , i.e, pointing in the direction towards D.
