SLAC, the Stanford Linear Accelerator Center, located at Stanford University in Palo Alto, California, accelerated electrons through a vacuum tube two miles long. Electrons which were initially at rest were subjected to a continuous force of 2×10−12 newton along the entire length of two miles (one mile is 1.6 kilometers) and reached speeds very near the speed of light.Determine how much time was required to increase the electrons' speed from 0.963c to 0.988c. (That is, the quantity ||/c increased from 0.963 to 0.988.)
