Question

Choose the correct answer
Property of anode rays :

• A. Travel in straight lines: They cast a shadow of the objects placed in their way.
• B. Produce mechanical effect: A paddle wheel placed in their path starts rotating.
• C. Rays are positively charged: Anode rays are deflected towards the negative plate of an electric field.
• D. All of the above

Answer 1

The correct option is D All of the above

Anode rays have the following properties:

$\left(i\right)$ Anode rays travel in straight line.

$\left(ii\right)$ Anode rays are material particles.

$\left(iii\right)$ Anode rays are positively charged.

$\left(iv\right)$ Anode rays may get deflected by external magnetic field.

$\left(v\right)$ Anode rays also affect the photographic plate.

$\left(vi\right)$ The $\frac{e}{m}$ ratio of these rays is smaller than that of electrons.

$\left(vii\right)$ Unlike cathode rays, their $\frac{e}{m}$ value is dependent upon the nature of the gas taken in the tube. It is maximum when gas present in the tube is hydrogen.
