An electron, after being accelerated through a potential difference of 100.0 V, enters a uniform magnetic eld of 0.0400 T perpendicular to its direction of motion. Calculate the radius of the path described by the electron Three identical charged particles sit at the corners of an equilateral triangle of side length 30 CL Each particle has a charge of 28.5 uC. Determine the magnitude and direction of the net force on each particle
