Complete the reactions. PCI_(5) (s) overset("Moist air")(rarr)

An electron enters a uniform magnetic field region such that the filed induction overset (rarr) B is parallel to the velocity overset (rarr) V of the electron. Then the electron will move

Complete the reactions. PCI_(3)(I) overset("Moist air")(rarr)

A charged particle of charge (+q) enters a region of uniform magnetic field of inductio overset (rarr) B with a velocity overset (rarr) V. the force experienced by the charged particle is

Correct the following statement. overset (rarr)|E| = -frac(dv)(dx) is correct.
