An electric dipole is placed as shown in the figure. The electric potential (in 10² V) at point P due to the dipole is (ε₀ = permittivity of free space and 1/(4πε₀)=K)

Asked in NEET 2023 · Potential of point charges

Figure: Potential of point charges
Answer: (1) (3/8)qK

Step-by-step solution

+q is 3 cm right of O and P is 5 cm right of O, so P is 2 cm from +q and 8 cm from -q.

V_P=Kq(1/(0.02)-1/(0.08))=Kq(50-12.5)=37.5 Kq V.

37.5 Kq=3/8Kq×10² V, so in units of 10² V the potential is 3/8qK.
