NOTE : When a charged particle enters a magnetic field at a direction perpendicular to the direction of motion, the path of the motion is circular. In circular motion the direction of velocity changes at every point (the magnitude remains constant).
Therefore, the tangential momentum will change at every point. But kinetic energy will remain constant as it is given by

1/2 mv² and v² is the squar e of th e magnitude of velocity which does not change.

A and B are two particles which start from rest. A has constant acceleration a = 3 m/s² in the direction shown. B also increases its speed at a constant rate b = 4m/s², but the direction of velocity is always towards A. If the time after which B meets A is 2lb b² a then, a (in Sl unit) is?

In the figure shown, A and B are two particles which start from rest. A has constant acceleration a = 3 m/s² in the direction shown. B also increases its speed at a constant rate b = 4m/s², but the direction of velocity is always towards A. If the time after which B meets A is 2lb b² a then, a (in Sl unit) is?
