Statement: Yukawa predicted the existence of `pi-` mesons.
Explanation: `pi-` mesons have their mass about 237 times more than electrons.

Assertion: An electron and proton enters a magnetic field with equal velocities, then, the force experienced by the proton will be more than electron. The mass of proton is 1837 times more than electron.

If electron in the atom is replaced by a particle (muon) having the same charge but mass about 200 times as that of the electron to form a muonic atom, how would : (i) the radius and (ii) the ground state energy of this be affected ?

An electron accelerated under a potential difference of V volt has a certain wavelength lamda It is known that the mass of a proton is about 1800 times the mass of an electron . If a proton has to have the same wavelength lamda , then it will have to be accelerated under the potential difference of

The radius of first Bohr orbit of hydrogen atom is 0.53Å . Then the radius of first Bohr-orbit of mesnoic atom (negative meson has mass 207 times that of electron but same charge) is:
