1) A long straight wire caring current I = 1.6 A as shown in Figure 1. An electron at distance of d = 1.00 cm from wire is moving with velocity of 90.0 m/s in positive x-direction. Find the direction and magnitude of magnetic force on the electron. In what location at a distance of d = 1.00 cm from the electron how many protons can we put to make the net force on electron at this condition be equal zero. Fig 1. Problem 1
