An electric field of 1500 Vm^-1 and a magnetic field of 0.40 Wbm^-2 act on a moving electron. The minimum uniform speed along a straight line the electron could have is

3.75 × 10³ ms⁻¹

Here, E = 1500 Vm^-1. B = 0.4 Wbm^-2

Minimum speed of electron along the straight line

$v = \frac{E}{B} = \frac{1500}{0.4} = 3750$

$ = 3.75× 10^3 ms^{-1}$
