Question

Two point charges – Q and 2Q are separated by a distance R, neutral point will be obtained at

• A. A distance of $\frac{R}{(\sqrt{2} - 1)}$from –Q charge and lies between the charges.
• B. A distance of$\frac{R}{(\sqrt{2} - 1)}$ from – Q charge on the left side of it
• C. A distance of $\frac{R}{(\sqrt{2} - 1)}$from 2Q charge on the right side of it
• D. A point on the line which passes perpendicularly through the centre of the line joining – Q and 2Q charge.

Answer 1

Answer: (B)

A distance of$\frac{R}{(\sqrt{2} - 1)}$ from – Q charge on the left side of it

Answer 2

As already we discussed neutral point will be obtained on the side of charge which is smaller in magnitude i.e. it will obtained on the left side of – Q charge and at a distance.
