please help this physics questions with clear steps and also with clear details, thank you (please take "a" as 9.81 and also with 4 decimal places and d7 =5 in this questions )

(b) A particle with a charge of 0.7C is moving parallel to a uniform magnetic field of (2+0.1*d7)T. The velocity of the charge is 330m/s. What is the magnitude of the magnetic force exerted on the particle? (c) A straight wire with a length of 24 cm carries a current of 5 A. The wire is making an angle of 450 to a uniform magnetic field of (3+0.1*d7) T. What is the size of the magnetic force exerted on the wire? (d) A magnetic field passes upward through a horizontal loop of wire as shown in Figure 6d. If the magnetic field increases with time, explain what will be the direction of the induced current as viewed from above? B Figure 6d
