Hey everyone, in this question we are given with a square of side length d.
00:05
So let's see the side length is d.
00:07
Now at three of its vertices, three charges of same magnitude are placed.
00:14
So let's say this is first charge having magnitude q but negative but negative in nature.
00:21
This is second charge again minus q and this is third charge again minus q.
00:26
The magnitude as well as nature of these three charges is same.
00:30
Now we have to have to find out direction of net electric field at the center of the square.
00:37
Now, as we know that if this distance is d, then this distance will be root 2 d by 2, that means d by root 2.
00:46
Okay, similarly, each and every charge is at same distance from the center of square, which is d by root 2.
00:55
So magnitude of electric field produced due to each charge at the center will be seen.
01:00
So let us consider if this is point here, then this negative charge will produce electric field towards it and let's say magnitude is e...
