How much time does it take for the partide to complete one revolution? t 1.6e-8 GO Tutorial Additional Materials Section 21 4 Submit Answer Save Progress My Notes Ask Your Teach 8. -2 points CJ10 21 P015 A charge particle enters a uniform magnetic field and follows the drcular path shown in the drawing (a) Is the particle positively or negatively charged negative electricaly reutral 0 8

Explanation / Answer

Ans 8.

here magntic field B is out of paper.

Force acting on particle is downwards,

if we use right hand rule, then direction of force will be upwards if charge was positive and B is inside the paper.

So taking the negative charge in consideration, will satisfy this situation.

..

Right hand rule,

thumb point towards direction of positive charge.

fingers in direction of magnetic field.

perpendicular to the palms gives us the direction of force.
