A coil of inductance

1\ \mathrm{H}

and resistance

10\ \Omega

is connected to a resistanceless battery of emf

50\ \mathrm{V}

at time

t=0

. Calculate the ratio of the rate at which magnetic energy is stored in the coil to the rate at which energy is supplied by the battery at

t=0.1\ \mathrm{s}
