Why is the particle emitted by the decay of the K-37 nucleus deflected away from
the positively charged plate?
The particle is a positron, which has a positive charge and is therefore repelled
by the positive charges on the plate.
The particle is an electron, which has a negative charge and is therefore repelled
by the positive charges on the plate.
