Two similar charge of magnitude q are fixed at distance of 2m. And another opposite charge of same magnitude is brought at center point between two charges and given a slight displacement along equatorial direction and released then angular frequency of oscillationd of opposite charge will be (value of `q^2 = 10 C^2`) (mass of opposite charge 0.2g)
