Q 14: a

Q 15: b

I think I found my explination are these releated?

The magnetic field in Fig. 32-29 points into the page. A small metal plane moves down the page. According to the pilot, which wing becomes negatively charged while the plane is moving? The left wing The right wing Neither wing becomes charged. The answer depends on the sign of the charge carriers in the plane. The plane is now turned around and "flies" to the top of the page. Which wing now becomes negatively charged while the plane moves up the page? The left wing The right wing Neither wing becomes charged. The answer depends on the sign of the charge carriers in the plane. Forces on charge carriers in a conductor in a magnetic field. Negative charge carriers (electrons) The charge carriers are pushed toward the top of the strip ... . so point a is at a higher potential than point b. Positive charge carriers The charge carriers are again pushed toward the ...so the polarity of the potential difference is opposite to that for negative charge carriers.

Explanation / Answer

14)

Here ,

as the force = q*V X B

force on the positive charge is to the right ,

Hence, the negative charge is on the lft ,

correct option is

A) the left wing

15)

for moving towards the top of the page ,

the force on positive charge changes the direction

and now the negative charge is on

B) the right wing
