Question

85636 016 (part 1 of 6) 10.0 points A particle of mass 6.64×10-26 kg and charge of magnitude 3.2 × 10-19 C is acceler- ated from rest in the plane of the page through a potential difference of 300 V between two parallel plates as shown. The particle is in jected through a hole in the right-hand plate into a region of space containing a uniform magnetic field of magnitude 0.0543 T ori- ented perpendicular to the plane of the page.

Answer 1

PART 1

As the particle is getting attracted to the negative plate of the capacitor, it should have positive charge. Hence option 2 is correct.

PART 2

The particle is getting pulled inside by magnetic force as result it is performing circular motion. By using

$F = q(\vec{v}\times \vec{B})$

the direction of magnetic force is determined. To generate an inside pull, the direction of magnetic field should be outside the plane of paper. Hence option 1 is correct.

PART 3-5

Part- Fromm work emy 2. 6 the article - 15 S-38 지0-1 a n/ As the十article. Part£ in par motion 2.

PART 5

The distance is 2r. That means answer is 2.37 cms.

PART 6

The magnetic force is always perpendicular to the displacement therefore the work done will be zero. Option 6 is correct.
