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?

The force becomes lesser to what it was.

F ∝ B

As B \(\neq \) zero, F \(\neq \) zero.
