Q.
The electrostatic force $({\vec{F}}_{1})$ and magnetic force $({\vec{F}}_{2})$ acting on a charge $q$ moving with velocity $v$ can be written [2024]

1 ${\vec{F}}_{1} = q \vec{B}, {\vec{F}}_{2} = q (\vec{B} \times \vec{v})$

2 ${\vec{F}}_{1} = q \vec{E}, {\vec{F}}_{2} = q (\vec{v} \times \vec{B})$

Solution

Q. The electrostatic force (F→1) and magnetic force (F→2) acting on a charge q moving with velocity v can be written [2024]

1 F→1=qB→,F→2=q(B→×v→)

2 F→1=qE→,F→2=q(v→×B→)

3 F→1=qv→·E→,F→2=q(B→·v→)

4 F→1=qE→,F→2=q(B→×v→)

Ans. (2) The electrostatic force acting on a charge, F→1=qE→ The magnetic force acting on a charge F→2=q(v→×B→)
