Three-point charges $+q$, $-2q$ and $+q$ are placed at points $(0,a,0)$, $(0,0,0)$ and $(a,0,0)$, respectively. The magnitude and direction of the electric dipole moment vector of this charge assembly are:

A nucleus has mass represented by $M(A,Z)$. If $M_p$ and $M_n$ denote the mass of proton and neutron respectively and $BE$ the binding energy, then:

The position $x$ of a particle with respect to time $t$ along the $x$ -axis is given by $x=9t^2-t^3$ where $x$ is in metre and $t$ in second. What will be the position of this particle when it achieves maximum speed along the $+x$ direction?

The total power dissipated in watts in the circuit shown here is:

In the following circuit, the output $Y$ for all possible inputs $A$ and $B$ is expressed by the truth table:ShutterstockExplore
