A charged particle of mass 10^-6 kg and charge 10^-6 C is placed in a uniform electric field of strength 10^4 N/C. What is the acceleration of the particle?
Correct: C
The force on the particle is given by F = qE, where q is the charge and E is the electric field strength. So F = (10^-6 C) * (10^4 N/C) = 10^-2 N. The acceleration of the particle is given by a = F / m, where m is the mass. So a = (10^-2 N) / (10^-6 kg) = 10^4 m/s^2.
