A doubly charged helium atom whose mass is 6.6 x 10-7 kg is accelerated by a voltage of 3000 V What will be its radius of cur

science physics

Answer 1

Answer #1

a)

Charge

Q=2e=2*1.6*10^-19=3.2*10^-19C

By Conservation of energy

(1/2)mv²=qV

v=sqrt[2qV/m] =sqrt[2*3.2*10^-19*3000/6.6*10^-27]

v=5.3936*10⁵ m/s

Here centripetal force is balanced by magnetic force

mv²/r =qvB

=>r=mv/qB =(6.6*10^-27)(5.3936*10⁵)/(3.2*10^-19)(0.39)

r=0.02852384 m

r=0.0285 m

b)

Period

T=2pir/v =2pi*0.0285/5.3936*10⁵

T=3.323*10^-7 s
