Electromagnetic waves are incident normally on a perfectly reflecting surface having surface area \( A \). If \( I \) is the intensity of the incident electromagnetic radiation and \( c \) is the speed of light in vacuum, the force exerted by the electromagnetic wave on the reflecting surface is

In an experiment to determine the temperature coefficient of resistance of a conductor, a coil of wire X is immersed in a liquid. It is heated by an external agent. A meter bridge set up is used to determine resistance of the coil X at different temperatures. The balancing points measured at temperatures \( t_1 = 0^\circ \text{C} \) and \( t_2 = 100^\circ \text{C} \) are 50 cm and 60 cm respectively. If the standard resistance taken out is \( S = 4 \, \Omega \) in both trials, the temperature coefficient of the coil is
