Two particles have equal mass m and electric charge of equal magnitude (q) and opposite sign. The particles are held at rest at co-ordinates (– a, 0) and (a, 0) as shown in the figure. The particles are released simultaneously. Consider only the electrostatic force between the particles and the force applied by the external magnetic field on them.

(a) Find the speed of negatively charged particle as function of its x co-ordinate.
(b) Find the y component of velocity of the negative particle as a function of its x co-ordinate.

Text Solution

Verified by Experts

The correct Answer is:
`(a) V=sqrt(kq^(2)/(2m)(1/x-1/a))" "(b) V_(y)=(qB)/(m)(a-x)`
