As the depletion region opposes flow of current due to majority charge carriers so reverse bias also being resistive to current flow inceases the width of depletion region. Option A is correct.

As plane of polarization (electric field vector) is always PERPENDICULAR to DIRECTION of propagtion of wave so it proves that light is a transverse wave.

As you know that the speed decreases to 1/n  times the speed in air where n is the refractve index of glass w.r.t. air while frequency remains constant.

and as the eqaution V = µ * wavelength holds true in both cases the wavelenth also decreases  to 1/n  times the wavelength in air.

Maxwell had given maxwell's equation for electrodynamic, where he coined the word displacement current between plates of a capacitor due to variable electric field.

Take help from formula.

As we know that induced emf is given as rate of change of magnetic flux of the coil, so focus on the parameter

(i)rate of change  ........... related to option D

(ii)flux of the coil.......   related to option A & C

so option B is correct as  resistance comes into play when induced current is to be calculated.

Force F is given as cross product of velocity and magnetic field multiplied my charge with sign.

So off course the force will be perpendicular to both V and B. (option D is correct)

As you know that power is P=i^2  * R   where R is external resistance (load) and i is current drawn by it .

While i   =  E /(R+r) where r is internal resistance.

For maximum power R=r so P becomes E^2   /4r 

option D may be correct after the correction:- there should be r in denominator alongwith 4 .

Torque is given by PESin ø, where ø is angle between field E and dipole moment P so if angle ø is zero or 180 degree only then torque will be zero while net force will be zero always because both charges will experience equal and opposite force .

opposite as both charges have opposite nature.

same force because same electric field in the region and same magnitude of charge as F=qE; so both q and E to be looked for analysis.

Note- Uniform electric field means same direction and magnitude at any point in the region of uniform field.
