When a known resistance `10Omega` and a conductor are connected in the right and left gaps of a meter bridge at `0^(@)C`.The balancing length is found to be 50cm. If the temp of the conductor is increased to `100^(@)C`; The balancing point is found to be at `52cm` .The temp coefficient of resistance of the material of the conductor is
1) `4.16times10^(-3)/(^@C)`
2) `8.33times10^(-4)/(^@C)`
3)`8.33times10^(-3)/(^@C)`
4) `4.16times10^(-4)/(^@C)`
