8) Experiment indicates that a superconductor having transition temperature of 4 K exhibit a penetration depth of 75 nm at 3.5 K. a) Determine the penetration depth as the temperature tends to reach 0 K. b) If the super electron density is 8.0×1028 m³ determine London penetration depth at zero Kelvin. Compare these two penetration depths.
