Dear Abhishek,

Electric potential is the work done in moving a unit charge from infinity to a point in an electric field.

Electric potential due to point charge:
V=−∫E? ⋅ds?
V=−∫Edscosϑ
if the stationary charge is positive and
if the test charge is is moved from infinity to point P
then
V=−∫Edscos180
V=−KQ1r2dscos180

Best Of luck
