r = mv/qB
They go in different direction but come out along parallel paths.
T = 2(π) m/qB
as m is different, so T is also different
3) An electron and a proton are moving on straight parallel paths with same velocity. They enter a semi-infinite region of uniform magnetic field perpendicular to the velocity. Which of the following statement(s) is/are true ?
Answer is:
They will come out travelling along parallel paths

Answer is:
((σA)/(σB)) = ((RA)/(RB))
Explanation:
1) EA = 0
2)(QA/RA) = (QB/RQB)
=>RA > RB
=>QA > QB
3)σ R = V
4) E = σ/(2 Eo
Answer is:
((Ne2)/(mEo))1/2
Explanation:
ω = θ/T = T-1
=>D.f. of ((Ne2)/(mEo))1/2 = (((1/L3)*(I2T2)*(ML3T-2))/(M*(I2T2)))
=> D.f = T-1
Answer is:
600nm
Explanation:
ω = 2π n
=> n= (ω)/(2π)
=>c=nλ
=>λ = c/n = (c2π)/(ω) = 66nm
Answer is:
Inertia
Explanation:
Newton's first law of motion - sometimes referred to as the law of inertia. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
