1. A charged particle \( q_{1} \) is at position \( (2,-1,3) \). The electrostatic force on another charged particle \( q_{2} \) at (f) 0,0 ) is : (1) \( \frac{q_{1} q_{2}}{56 \pi \epsilon_{0}}(2 \hat{i}-\hat{j}+3 \hat{k}) \) (2) \( \frac{q_{1} q_{2}}{56 \sqrt{14 \pi} \epsilon_{0}}(2 \hat{i}-\hat{j}+3 \hat{k}) \) (3) \( \frac{q_{1} q_{2}}{56 \pi \epsilon_{0}}(\hat{j}-2 \hat{i}-3 \hat{k}) \) (4) \( \frac{q_{1} q_{2}}{56 \sqrt{14} \pi \epsilon_{0}}(\hat{j}-2 \hat{i}-3 \hat{k}) \)

Two equal positive point charges are separated by a distance \( 2 a \). The distance of a point from the centre of the line joining two charges on the equatorial line (perpendicular bisector) at which force experienced by a test charge \( q_{0} \) becomes maximum is \( \frac{a}{\sqrt{x}} \). The value of \( x \) is

Charges \( -q \) and \( +q \), located at \( A \) and \( B \), respectively, constitute an electric dipole. Distance \( A B=2 a, O \) is the mid point of the dipole and \( O P \) is perpendicular to \( A B \). A charge \( Q \) is placed at \( P \) where \( O P=y \) and \( y \gg 2 a \). The charge \( Q \) experiences an electrostatic force \( F \). If \( Q \) is now moved along the equatorial line to \( P^{\prime} \) such that \( O P^{\prime}=\left(\frac{y}{3}\right) \) the force on \( Q \) will be close to \( \left(\frac{y}{3} \ll 2 a\right) \)

5. Apoint charge \( q _{1}=4 q _{0} \) is placed at origin. Another point charge \( q _{1}=- q _{0} \) is placed at \( x =12 cm \). Charge of proton is \( q _{0} \). The proton is placed on \( x \)-axis so that the electrostatic force on the proton is zero. In this situation, the position of the proton from the origin is \( cm \). [Jan. 29, 2023 (I)]
