From Newton's second law of motion, we understand that the acceleration of an object depends on two factors: The mass of the object and the net force acting on the object.
F = m a
For an object, mass remains constant. So, only by altering the net amount of force, the acceleration can be changed.
a ∝ F
Thus, when the net force would be increased, the acceleration of the object would increase.
Beta radiation is a radioactive phenomenon of nuclear decay in which an unstable atom or isotop, by transforming a neutron into a proton, or by transforming a proton into a neutron, becomes stable. For example, the decay of carbon 14 produces beta radiation.
