Answer:
Explanation:
Two point charges are placed at two end of a line,
Charge on each charge =
Distance by which they are separated= 50cm=0.5m
We have to find the electric field at the center which is 0.25m away from charge.
From the figure we can see that
is also same but opposite in direction ⇒
Hence the net electric field at the center is =
