Explanation:
We have given mass of alpha particle m = 4 u
Charge on alpha particle
Charge on thorium particle
Diameter is given as d = 15 fm
So radius
Potential energy is given by
From energy conservation
In order to get the best result, the student should heat the salt water mixture gently.
Application of heat will increase the amount of the kinetic energy that is available to the molecules of the salt, the particles will be moving faster and in the process they will dissolve faster. Application of heat will make the water molecules too to gain energy and take in more salts more rapidly.
