Question

an Alpha particle Travels along the inside of a straight hollow tube, 2.0 M long, of a particle accelerator. under uniform acceleration, how long is the particle in the tube if it enters at a speed of 1000 m/sec and leaves at 9000 m/sec ?

Answer 1

ANSWERS :-


SOLUTION :-

Let a be the uniform acceleration of alpha-particle.

A/q

S = 2.0m

V = 9000 m/sec

U = 1000 m/sec


Now ,

V² – U² = 2as

a = v² – u²/2s

a = (9000)² – (1000)² / 2 * (2.0)

= 8 * 10^7 /4.0

= 2.0 * 10^7 m/sec²

acceleration = 2 * 10 ^7 m/ sec ²

Answer 2

Answer:

9000 = 1000 + at

at = 8000

s = ut + at^2/

= 8000t + 8000t /2

4= 12000t

t = 1/3000

= .00033

3 * 10^-3

= a = 8000000/3
