Problem 1: A stationary electric charge q =2 .6 × 10 -8 C is placed in a laser beam whose intensity is 2.5 × 10 3 W/m 2 . Determine the magnitude of the (a) electric and (b) agnetic rces xerted n e harge e harge ow oving erpendicular magnetic forces exerted on the charge. If the charge is now moving perpendicular to the magnetic field with a speed of 3.7 × 10 4 m/s, find the magnitudes of the (c) electric and (d) magnetic forces exerted on it.

Problem 2 – A tiny bulb is emitting light uniformly in all directions. At a distance of 2.5 m from the source, the electric field has a maximum value of 26.9 N/C. ssuming at e ht oes ot flect om nything e nvironment Assuming that the light does not reflect from anything in the environment, calculate the average power of the light emitted by the source.
