A particle of mass m and charge q is in a uniform electric field of strength E. The particle has acceleration a due to the field. The particle has a charge of 4e where e is the elementary charge. The electric field strength is 3.5 × 10⁴ V m⁻¹. The acceleration of the particle is 1.5 × 10¹²ms⁻². A second nucleus that is an isotope of the nucleus in (c) is in the same uniform electric field.
