A particle with a charge of 5*10^-⁶ C and a mass of 20 g moves uniformly with a speed of 7 m/s in a circular orbit around a stationary particle with a charge of -5 *10^-⁶ C. The radius of the orbit is:

Question

Quizplus · Accepted Answer

The correct answer is B because the radius of the orbit is given by the equation r = (mv^2)/(qB), where m is the mass of the particle, v is its speed, q is its charge, and B is the magnetic field strength. In this case, the magnetic field strength is zero, so the radius of the orbit is infinite.
