A cosmic ray muon with the same charge as an electron and a mass of 1.9 × 10-28 kg is moving toward the ground at an angle of 25° from the vertical with a speed of 7.0 × 107 m/s. As it crosses point P, the muon is at a horizontal distance of 85.0 cm from a high-voltage power line. At that moment, the power line has a current of 16.0 A. What is the magnitude and direction of the force on the muon at the point P in the diagram?
