Two equal negative charges –q are fixed at points (o, a) and (o, –a) on the Y axis. A
positive charge q is released from rest at the point `x (x < < a)` on the X-axis, then the
frequency of motion is .........
Options:
(a) `sqrt(q^2/(πepsilon_o ma^3)`
(b) `sqrt((2q^2)/(4πepsilon_o ma^3)`
(c) `sqrt((4q^2)/(2πepsilon_o ma^3)`
(d) `sqrt(q^2/(2πepsilon_o ma^3)`
