Question

Plz do it fast....
I want no solution only answer...but correct...​

Answer 1

Answer:

3.

$qvb = \frac{m {v}^{2} }{r} \\ \\ r = \frac{mv}{qb} = \frac{ \sqrt{2mk} }{qb}$

Answer a

4. (b)

$t = \frac{2\pi \: m}{qb}$

So time period of proton will be higher since mass is higher then electron

5. (a)

$r = \frac{mv}{qb} = \frac{mv}{eb} \implies \frac{e}{m} = \frac{v}{br}$

6. (a)

7. (c)

$r = \frac{mv}{qb} = \frac{p}{qb}$
