Q. 585.0( 4 Votes )

An electric field exists in the space. If the potential at the origin is taken to be zero, find the potential at (2m, 2m).

Answer :

Electric field: = 20+ 30
V(0,0) = 0
Final position:

Formula used:
We know that Electric potential is given as:
Where ds is the change in displacement.
In vector form
Here, r̅ is the changed position from origin.

Hence potential at (2m,2m) is -100 V.
