State which of the following is correct
$Joule = coulomb × volt$
$Joule = coulomb/volt$
$Joule = volt × ampere$
$Joule = volt / ampere$
Assertion : Electric potential and electric potential energy are different quantities.
Reason : For a system of positive test charge and point charge electric potential energy $=$ electric potential.
How much kinetic energy will be gained by an $\alpha - $particle in going from a point at $70\,V$ to another point at $50\,V$
Three charges $-q, Q$ and $-q$ are placed respectively at equal distances on a straight line. If the potential energy of the system of three charges is zero, then what is the ratio of $Q: q$ ?
When a proton is accelerated through $1\,V$, then its kinetic energy will be.....$eV$
A particle of mass $m$ and charge $q$ is placed at rest in a uniform electric field $E$ and then released. The kinetic energy attained by the particle after moving a distance $y$ is
