Which of the following particle has similar mass to electron
Proton
Neutron
Positron
Neutrino
(c) Electron and Positrons are anti-particles.
and anti-particles have same mass.
In the nuclear reaction $_{92}{U^{238}}{ \to _z}T{h^A}{ + _2}H{e^4}$, the values of $A$ and $Z$ are
A nucleus disintegrates into two smaller parts, which have their velocities in the ratio $3: 2$. The ratio of their nuclear sizes will be $\left(\frac{x}{3}\right)^{\frac{1}{3}}$. The value of ' $x$ ' is :
Assertion : The binding energy per nucleon, for nuclei with atomic mass number $A > 100$, decreases with $A$.
Reason : The nuclear forces are weak for heavier nuclei.
Mention the total charge of electron in the atom.
Two nuclei have their mass numbers in the ratio of $1 : 3.$ The ratio of their nuclear densities would be
