A) Consider two metal plates separated by a dielectric material with a thickness of 4.5 cm. If the lower plate is at a potential of 9 V and the upper plate is at a potential of 0 V, what is the magnitude of the electric field generated between the plates? a) 200 V/m b) 40.5 V∙m c) 0.405 V∙cm d) 2 V/m   B) What force will a proton feel in the uniform electric field from the question above? a) 32 N [towards upper plate] b) 3.2 x 10-17 N [towards upper plate] c) 6.48 x 10-18 N [towards lower plate] d) 64.8 N [towards lower plate]

Considering electron and proton as two charged particles separated by d = 4.3 x 10-11 m calculate the electrostatic potential at a distance d from the proton. Take the mass of the proton 1.7 x 10-27 kg, the mass of the electron 9.1 x 10-31 kg, the electron charge -1.6 × 10-¹⁹ 1 C and = 9 × 10⁹ m/F. Απευ Answer: Choose...
