Two identical tennis balls each having mass 'm' and charge ' q ' are suspended from a fixed point by threads of length . What is the equilibrium separation when each thread makes a small angle with the vertical ? [27 Jul 2021 Shift 1]l '. What is the equilibrium separation when each thread makes a small angle ' \θ' with the vertical ? [27 Jul 2021 Shift 1] \\theta' with the vertical ? [27 Jul 2021 Shift 1]l '. What is the equilibrium separation when each thread makes a small angle ' \θ' with the vertical ? [27 Jul 2021 Shift 1]

Correct Answer is : x=(q2l2πε0mg)13

x=({q^{2} l}/{2 \\pi\\epsilon_{0} m g})^{\frac{1}{2}}

x=({q^{2} l}/{2 \\pi\\epsilon_{0} m g})^{\frac{1}{3}}

x=({q^{2} l^2}/{2 \\pi\\epsilon_{0} m ^2g})^{\frac{1}{2}}

x=({q^{2} l^2}/{2 \\pi\\epsilon_{0} m ^2g^2})^{\frac{1}{2}}
