In an electromagnetic wave in free space the root mean square value of the electric field is $E_{rms}=6\text{V/m}$. The peak value of the magnetic field is:

The bulk modulus of a spherical object is ‘$B$ ’. If it is subjected to uniform pressure ‘$p$ ’, the fractional decrease in radius is:

The ratio of resolving powers of an optical microscope for two wavelengths ${\lambda }_1=4000\text{A˚}$ and ${\lambda }_2=6000\text{A˚}$ is:

Consider a drop of rain water having mass $1\text{g}$ falling from a height of $1\text{km}$. It hits the ground with a speed of $50\text{m/s}$. Take $g$ constant with a value $10{\text{m/s}}^2$. The work done by the (i) gravitational force and the (ii) resistive force of air is:

A spherical black body with a radius of $12\text{cm}$ radiates $450\text{watt}$ power at $500\text{K}$. If the radius were halved and the temperature doubled, the power radiated in watt would be:
