An electron enters a region of space containing a uniform 0.103-t magnetic field. its speed is 149 m/s and it enters perpendicularly to the field. under these conditions, the electron undergoes circular motion. find the radius r of the electron\'s path, and the frequency f of the motion.

Explanation:

Given

B=

velocity

mass of electron

charge on electron

We know

For frequency we need to know time period

-4 on

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
