Question

03: An electron emitted from a source is subjected to a force of 10-2' N and the electron is accelerated towards the target. Find The acceleration of electron b. How long does the electron reach from source to target of distance 10cm a.​

Answer 1

Answer:

The acceleration of the electron

a=Fm=10−2510−30=105ms−2

The time taken by the elecron (t) to cover the distance (s) of 0.2m can be given by

s=ut+12at2

⇒0.2=0+12×105×t2

⇒t2=0.4×10−5=4×10−6⇒t=2×10−3s

Answer 2

Answer:

acceleration= 1.09×10⁷ms-²

time= 1.35×10-⁴
