Q. Photons of wavelength 490 nm are incident on a metal. The most energetic electrons ejected from the metal are bent into a circular arc of radius 10.7 cm by a magnetic field with a magnitude of 1.86x10^-5T. What is the work function of the metal?

Q. A circuit contains six 210 lamps and a 14.0 heater connected in parallel. The voltage across the circuit is 120 V. If the circuit has a 12 A fuse, will the fuse melt if all the lamps and the heater are on?
