Beta particles come from the nucleus. Electrons are found around the nucleus.
Beta particles normally travel very fast out of a nucleus in a straight line. Electrons normally orbit the nucleus of an atom.
They both have the same mass and the same charge.

Explanation:
The acceleration due to gravity on earth is given by
where = universal gravitational constant
= mass of the earth
= radius of the earth
Planet Krypton has twice the mass of earth and 3 times the radius so its acceleration due to gravity is
or
If we multiply both sides by Superman's mass, we get his weights on both planets:
