If two different particles of same initial velocity and charge fall perpendicularly into a uniform magnetic field and follows a circular path, then:

In a steady flow reversible adiabatic process, work done is equal to:

As per the Bohr model, the minimum energy (in eV) required to remove an electron from the ground state of a double ionized Li atom (Z = 3) is:

Let \(\mathrm{x}=\left[\frac{\mathrm{a}^{2} \mathrm{~b}^{2}}{\mathrm{c}}\right]\) be the physical quantity. If the percentage error in the measurement of physical quantities \(a\), \(\mathrm{b}\) and \(\mathrm{c}\) is 2, 3 and 4 percent respectively then percentage error in the measurement of \(\mathrm{x}\) is:
