(i) Let us consider Charge of particle is q and velocity is v then if Charge will move in Magnetic field B normal to the magnetic field then theta = 90

F = qv B Sintheta

F = qvBSin90
F = qvB Newton

(II)Let us consider Charge of particle is q and velocity is v then if Charge will move in Magnetic field B normal to the magnetic field then theta = 45

F = qv B Sintheta

F = qvBSin45
F = qvB / sqrt (2) Newton

(iii)Let us consider Charge of particle is q and velocity is v then if Charge will move in Magnetic field B normal to the magnetic field then theta = 0

F = qv B Sintheta

F = qvBSin0
F = 0 Newton
