Question

Which nuclear emission moving through an electric field would be deflected toward the positive electrode?

A.) Alpha Particle
B.) Beta Particle
C.) Gamma Radiation
D.) Proton

Answer 1

A beta particle, which is essentially a high-speed electron, would be deflected toward the positive electrode in an electric field due to its negative charge. So the correct option is B.

Step-by-step explanation:

The nuclear emission that would be deflected toward the positive electrode when moving through an electric field is a beta particle. A beta particle is essentially an electron ejected from the nucleus, which carries a negative charge (represented as e- or β). As such, it is attracted to the positive electrode. This behavior can be explained by the fact that charged particles experience a force when they move through an electric field, which causes them to accelerate toward the electrode of the opposite charge. Alpha particles, being positively charged, are attracted to the negative electrode instead, while gamma rays, which are uncharged, do not get deflected by the electric field at all.

Answer 2

As a rule, opposite charges attract. So,you would expect that the particle that would deflect towards the positive electrode has a negative charge. Now, an alpha particle is basically a neutral Helium atom. Beta particle is an electron. Gamma particle has no charge (neutral). Thus, the answer is B.
