Options:

In the product $\vec{F}=q(\vec{v}\times \vec{B})=q\vec{v}\times (B_0\hat{i}+B_0\hat{j}+B_z\hat{k})$.For $q=1$ and $\vec{v}=2\hat{i}+4\hat{j}+6\hat{k}$ and $\vec{F}=4\hat{i}-20\hat{j}+12\hat{k}$, what will be the complete expression for $\vec{B}$?

A car starts from rest and accelerates at $5{\text{m/s}}^2$. At $t=4\text{s}$, a ball is dropped out of a window by a person sitting in the car. What is the velocity and acceleration of the ball at $t=6\text{s}$? ($g=10{\text{m/s}}^2$)

Three resistors having resistance $r_1,r_2$, and $r_3$ are connected as shown in the given circuit. The ratio $i_3/i_1$ of currents in terms of resistances used in the circuit is:

A point object is placed at a distance of $60\text{cm}$ from a convex lens of focal length $30\text{cm}$. If a plane mirror were put perpendicular to the principal axis of the lens and at a distance of $40\text{cm}$ from it, the final image would be formed at a distance of:
