An electron with velocity 3 * 10^7 ms-1 describes a circular path in a uniform megnatic field of 0.2T, perpendicular to it. Calculate the radius of path.

Answer 1

R=mv/eB
m =9.1•10 ⁻³¹kg
e =1.6•10⁻¹⁹ C.

Answer 2

Pls anwer

Answer 3

an electron with velocity 3×10 '7m/s describes a circular path in a uniform magnetic field 0.2t perpendicular to it calculate the radius of the path
