Assertion: In Hertz experiment, the electric vector of radiation produced by the source gap is parallel top the gap.
Reasion: Production of sparks between the detector gap is maximum when it is placed perpendicular to the source gap.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reasion are true but reason is not the correct explanation of assertion.

C

If assertion is true but reasion is false.

D

If assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
c
Hertz experimentally observed that the producation of spark between the detector gap is maximum when it is placed parallel to source gap. This means that the electric vector of radiation produced bby the source gap is parallel to the two gaos i.e., in the direction perpendicular to direction of propagation of the radiation.

An electron (charge = e, mass = m) is projected horizontally into a uniform electric field produced between two oppositely charged parallel plates, as shown in figure. The charge density on both plates is +- sigma C//m^2 and separation between them is d. You have to assume that only electric force acts on the electron and there is no field outside the plates. Initial velocity of the electron is u, parallel to the plates along the line bisecting the gap between the plates. Length of plates is 2L and there is a screen perpendicular to them at a distance L. (i) Find s if the electron hits the screen at a point that is at same height as the upper plate. (ii) Final the angle q that the velocity of the electron makes with the screen while it strikes it.

The gap between the plates of a parallel-plate capacitor is filled with istropic dielectrc whose permittlvity epsilon varies linearly from espilon_(1) to epsilon_(2) (epsilon_(2) gt epsilon_(1)) in the direction perpendicular to the plates. The area of each plate equals S , the separation between the plates is equal to d . Find : (a) the capacitance of the capacitor, (b) the space density of the bound chagres as a function of a if the charge of the capacitor is q and E in it is directed toward the growing epsilon values.

In a meter-bridge experiment, two resistances P and Q are connected in series in the left gap. When the resistance in the right gap is 50Omega , the balance point is at at the centre of the slide wire. If P and Q are connected in parallel in the left gap, the resistance in the right gap has to be changed to 120Omega so as to obtain the balance point at the same position. find P and Q.
