Question:

What is the electric potential at the point indicated with the dot in the figure?

Answer and Explanation:

Electric Potential:
The electric potential at a point that is rr away from a solitary charge Q is given by
V = kQ/r
where k=1/4πϵ0 ≈ 8.99×109 Nm2/C2 alluded to as the Coulomb’s consistent.
For numerous charges, the net electric potential at the fact is the scalar aggregate of the potential because of each charge.
Answer and Explanation:
To begin with, we decide r:
r= (3.0 cm/2) cos30∘=1.299 cm=1.299×10−2 m
At that point we let
• Q1=1.0 nC
• Q2=Q3=−2.0 nC
Review that the electric potential at a point because of a point charge is given by
V=kQr
where
• k=8.99×109 Nm2/C2 is the estimation of Coulomb’s consistent
• Q is the charge
• r is the separation of the charge from the point
Henceforth, the net electric potential at the point for this situation is the total of the possibilities because of each charge:
Vnet = V1 + V2 + V3
=kQ1/r+kQ2/r+kQ3/r
=kr[Q1 + Q2 + Q3]
=8.99×109 Nm2/C2/1.299×10−2 m + x [1.0 nC − 2.0 nC − 2.0 nC]
= −2076.2 V
