A microscopic spherical dust particle of radius 2.1 μm and mass 9.5 μg is moving in outer space at a constant speed of 35 cm/s. A wave of light strikes it from the opposite direction of its motion and gets absorbed. Assuming the particle decelerates uniformly to zero speed in one second, what was the maximum amplitude of the electric field of the radiation that was absorbed? Give your answer in volts per meter.

A negatively charged particle enters a region between two parallel plates. Each plate (top and bottom) are oppositely charged, hence the exists a uniform electric field between the plates along with a gravitational field). Assume the particle travels the region straight through completely un-deflected and exits. a) Determine and identify below) te polarities of the plates and the resulting Electric Field direction inside the plated region needed so the particle travels through un-deflected: b) If the particle has a mass...

A pair of closely spaced parallel conducting plates, charged with equal and opposite electric charges, produces a uniform electric field in the region between them. In designing a cutting-edge device that will revolutionize the electronics industry, you set up such a pair of plates with a separation of 0.953 mm between them and charge them so that the direction of the electric field in their interior region is from plate A to plate B. Your idea requires that electrons, when...
