Question

Two tiny spheres carrying charges $1.8\mu C$ and $2.8\mu C$ are located at $40cm$ apart. The potential at the mid-point of the line joining the two charges is

• A. $4.3\times 10^{4}V$
• B. $3.6\times 10^{5}V$
• C. $3.8\times 10^{4}V$
• D. $2.1\times 10^{5}V$

Answer 1

Answer: (D)

$V=\frac{k{q}_1}{r_1}+\frac{k{q}_2}{r_2}$
