Question

please show all work! thank you

13) Use the right-hand rule to determine the direction of the magnetic field or force where appropriate. (a) If a negative charge has a velocity vin an external magnetic field B then in what direction is the force. (b) If a positive charge has a velocity v in an external magnetic field B then in what direction is the force. O O O O O ооооовое ооооо (c) If a positive charge has a velocity v and the force F acting on it is into the page then what is the direction of the magnetic field?

Answer 1

Selection we know that the force on the charge is given as P = q V x B so we will colour Right hand from v to B q the chrrection of thumb will give the direction of (a) the charge is negative q=-9 F = -9 V x B f = g (B x 3 Here we will curl fingure from B to v

0 0 0 0 0 7 - 9 V XP 0 to A tue Ñ to B T ra direction of force. Bout (6) Here charge is the charge when we cell our fingure from i to B it muust gives us the clirection in order to get ŕ the Ŝ will be in this direction.
