$A$ proton is accelerated through a potential difference of $1 \,V$. The kinetic energy $(KE)$ of the proton will be $....... \,eV$.

$A$ particle of charge $Q$ and mass $m$ travels through a potential difference $V$ from rest. The final momentum of the particle is

Four point charges $-Q, -q, 2q$ and $2Q$ are placed,one at each corner of a square. The relation between $Q$ and $q$ for which the potential at the center of the square is zero is:

Let $W$ joule be the work done to move an electric charge $q$ coulomb from a place $A$,where potential is $-5 \ V$,to another place $B$,where potential is $V$ volt. The value of $V$ is
