We note that the atomic number of Th is 92. That is a nucleus of Th has
units of
charge; and that the atomic number of He is 2 and it has
units of charge. Therefore, at the instant when
particle is
from the
particle,
the magnitude of the electrostatic force on it will be

(b)
Molar mass of
is 4.0026
g. Therefore, rest mass of a
particle
will be

Acceleration of the
particle
at that instant, if calculated using the Newtonian mechanics, will be

But as the
particle
will be relativistic, we should use its relativistic mass in calculating its
acceleration.
