Two electrons move near each other and at the instant shown in Figure P28.85 are \(2.0 \mathrm{~mm}\) apart. The speed of electron 1 is \(v_{1}=300 \mathrm{~m} / \mathrm{s}\), that of electron 2 is \(v_{2}=\) \(500 \mathrm{~m} / \mathrm{s}\), and the directions of motion are as shown in Figure P28.85. Determine the magnitude and direction of \((a)\) the magnetic force exerted by electron 1 on electron 2 and \((b)\) the magnetic force exerted by electron 2 on electron 1.
