    q27... one way to look is that no displacement is covered in the direction of the force... so no work is done... secondly, force and displacement has an angle of 90 in between.. so fdcosx will again be zero... thirdly, both P and Q are at the same potential.. so moment of charges at same...

    q25... c=f(lambda) for the given length of loop, which is equal to half the wavelength, we have, speed=f(1/2lambda) for complete wave now, speed wont change, so wavelength is doubles as before, so inorder to maintain constant speed, frequency has to be doubled to...
