165682 An electric circuit requires a total capacitance of $2 \mu \mathrm{F}$ across a potential of $1000 \mathrm{~V}$. Large number of $1 \mu \mathrm{F}$ capacitances are available each of which would breakdown if the potential is more than $350 \mathrm{~V}$. How many capacitances are required to make the circuit?
