An X-ray tube has three main controls. ...


An X-ray tube has three main controls.
(i). The target material (its atomic number Z)
(ii). The filament current `(l_(f))` and
(iii). The accelerating voltage (V)
Figure shown a typical intensity distribution against wavelength which of the following si incorrect?

A

The limit `lamda_(min)` is proportional to `V^(-1)`

B

The sharp peak shifts to the right as Z is increased

C

The penetrating power of X ray increases if V is increased

D

The intensity everywhere increases if filament current `l_(f)` is increased

Text Solution

Verified by Experts

The correct Answer is:
B
As accelerating voltage is increased, energy increases, the `lamda_(min)` decreases and X-rays are getting harder (less wavelength) and penetrating power increases if filament current increases, more electrons are emitted.

A rigid wire loop of square shape having side of length L and resistance R is moving along the x-axis with a constant velocity v_(0) in the plane of the paper. At t=0 , the right edge of the loop enters a region of length 3L where there is a uniform magnetic field B_(0) into the plane of the paper, as shown in the figure. For sufficiently large v_(0) , the loop eventually crosses the region. Let x be the location of the right edge of the loop.
