Case : Read the passage and answer the question(s).
A force on a charge in electric and magnetic field is given as :
F = qE + qvB
where,
E : Electric field
B : Magnetic field
q : Charge
v : Velocity of the charge
Based on this information, answer the question that follows.
At an instant of time, the magnetic field is turned to half the original value. Which of the following is incorrect?
Answer & explanation
Correct answer: option 4
F ∝ B
As B \(\neq \) zero, F \(\neq \) zero.
