Problem

Two parallel wires in the plane of the paper are distance

X_0

apart. A point charge is moving with speed

u

between the wires in the same plane at a distance

X_1

from one of the wires. When the wires carry current of magnitude

I

in the same direction, the radius of curvature of the path of the point charge is

R_1

. In contrast, if the currents

I

in the two wires have directions opposite to each other, the radius of curvature of the path is

R_2

. If

\frac{X_0}{X_1} = 3

, the value of

\frac{R_1}{R_2}

is [Adv. 2014]
