155525 The amplitude of the electric field in a parallel beam of plane electromagnetic waves of intensity $53.1 \mathrm{~W} \mathrm{~m}^{-1}$ is
(Permittivity of free space $=8.85 \times 10^{-12} \mathrm{C}^{2} \mathrm{~N}^{-1}$ $\mathbf{m}^{-2}$ )

155521 Assertion: If a charged particle is released from rest in a region of uniform electric and magnetic fields parallel to each other, it will move in a straight line.
Reason: The electric field exerts no force on the particle but the magnetic field does.
