Q6 CQ - College Physics (Urone)

Question

If an electric field is substituted for the magnetic field with positive charge instead of the north pole and negative charge instead of the south pole, in which directions will the α , β , and γ rays bend?

Step-by-Step Solution

Answer

\({\rm{\alpha }}\) Ray bends toward negative charge. \({\rm{\beta }}\) Ray bends toward positive charge. \({\rm{\gamma }}\)Ray remains unaffected.

Step 1 Definition of electric field

An electric field is a physical field that surrounds electrically charged particles and acts as an attractor or repellent to all other charged particles in the vicinity.

Step 2: Directions of α , β , and γ rays bend

If magnetic field is substituted by an electric field, north-pole by positive charge and south-pole by negative charge then \({\rm{\alpha }}\) rays will bend towards negative charge because \({\rm{\alpha }}\) rays are positively charged and \({\rm{\beta }}\)rays will bend towards positive charge because \({\rm{\beta }}\) rays are negatively charged and their mass and charge to mass ratio is similar to that of electron. \({\rm{\gamma }}\) Rays being neutral charged remains unaffected.

Therefore, \({\rm{\alpha }}\) Ray bends toward negative charge. \({\rm{\beta }}\) Ray bends toward positive charge. \({\rm{\gamma }}\)Ray remains unaffected.
