Q1. A particular nucleus of the element plutonium contains 94 protons and 150 neutrons. What is the magnitude of the force from the nucleus on a single electron that is at a distance of 0.563 × 10-12 m from the plutonium nucleus?

Q2. A piece of aluminium (specific heat 0.910 kJ/kg 0C) of mass 161 g at 75 0 C is dropped into the Styrofoam cup filled with 181 ml water at 20 0 C. What are the final temperatures of the water and the aluminium?

Hint 1: since the cup is well-insulated, you can assume that all the heat leaving aluminium as it cools goes to heating the water.

Hint 2: How are the final temperature of aluminium related to the final temperature of the water?
