Answer:
\frac{R}{^{\sqrt{2}}}
Explanation:
q1 = q , q2 = q
m1 = M, m2 = 2M
Potential difference is V
Let v1 be the speed of first particle and v2 be the speed of second particle.
Energy due to potential difference gives the kinetic energy to the particle.
1/2 m x v^2 = e V
v^2 = 2 e V / m = 2e V / m ... (1)
Now radius is given by
r = m v / B q
by eqution (1)
For first particle
.... (2)
For second particle
.... (3)
Divide equation (2) by equation (3), we get
So
r1 / r2 =
