May I get clear explanation how to work these with diagrams where necessary. Thank you

1. (25 Points) A particle (mass = 6.0 mg) moves with a speed of 4.0 km/s in a direction that makes an angle of 370 above the positive x axis in the xy plane. At the instant it enters a magnetic field of (5.0i) mT it experiences an acceleration of (8.0k) m/s. What is the charge of the particle?2. (25 points) Three long wires parallel to the x axis carry currents as shown. If I = 20 A, what is the magnitude of the magnetic field at the origin? 41 y =2m X y=-1m 31 y=-3m3. (25 Points) A flat coil of wire consisting of 20 turns, each with an area of 50 cm2, is positioned perpendicularly to a uniform magnetic eld that increases its magnitude at a constant rate from 2.0 T to 6.0 T in 2.0 s. If the coil has a total resistance of 0.40 Q, what is the magnitude of the induced current
