In these question, a statement of asertion followed by a statement of reason is given .Choose the correct answer out of the following choices: Assertion and reason both are correct statements and reason is correct explanation for assertion. Assertion and reason both are correct statements but reason is not correct explanation for assertion. Assertion is correct statement but reason is wrong statement. Assertion is wrong statement but reason is correct statement. Assertion:the pairs E_x,B_y nd E_y,B_x ,components of space and time varying electric field overset vec (E) and magnetic field oversetvec(B) can generate a plane electromagnetic wave travelling along the Z-direction. Reason:It is because,electromagnetic waves propagae in the direction of vectro overset vec E xx overset vec B .

The electric potential V(x) in a region along the X-axis varies with the distance x (in metre) according to the relation V(x) = 4x^2 . Calculate the force experienced by a 1muC charge placed at point x = 1 m.

One end of a long string of linear mass density 8.0 xx 10^-3 kg m^-1 is connected to an electrically driven tuning fork of frequency 256 Hz. The other end passes over a pulley and is tied to a pan containing a mass of 90 kg. The pulley end absorbs all the incoming energy so that reflected waves at this end have negligible amplitude. At t= 0, the left end (fork end) of the string x = 0 has zero transverse displacement (y = 0) and is moving along positive y-direction. The amplitude of the wave is 5.0 cm. Write down the transverse displacement y asfunction of x and tthat describes the wave on the string
