Question

An electron at point A in figure has a speed $v_{o} = 1.41 \times 10^{6} m / s$ . Find the time required for the electron to move from A to B.

Open in App

Solution

Time period= $T = \frac{2 π r}{v} = 2.22 \times 10^{- 7} s$
Hence time taken by electron to move from A to B is $\frac{T}{2}$
$= 1.11 \times 10^{- 7} s$
