An electron travels with a speed of (7.80×10^4) m/s along the x-axis.
An electron travels with a speed of (7.80×10^4) m/s along the x-axis. A uniform magnetic field of strength (7.7×10^-4) T directed along the y-axis is turned on, and the electron starts travelling in a circle due to the magnetic force. What is the radius of this circle?Give your answer in meters (m) using scientific notation.
Note: Your answer is assumed to be reduced to the highest power possible.
