Find : a. current equivalent in mA ? b. How many charges are transferred ? c. How much work is required to transfer if 3V is applied. 3. A charge of 3.5 uC present in an electric field produces a force of 0.008 Newton. What is the intensity of the electric field ? 4. A charge of 0.6 UC is placed in an electrostatic field whose intensity is 3 x 105 N/C. How strong is the force acting on the charge ? 5. Two objects are both negatively charge with 0.04 coulomb each and 140 cm apart. What kind of force exist Between charges? How much ? 6. Find the force that exist between two charges of 8.53 uC and 4.5 JC that 0.25 meters in air ?Law of Heat Exchange and Change of Phase Solve the following problems; 1. How many calories of heat are needed to raise the temperature of 75g of water from 20 . C to 80 . C. How much heat is liberated when 50g of water is cooled from 100 * C to 20 . C One hundred grams of aluminum at 100" C is mixed with 100 g of water at 10 * C. What is the final temperature of the mixture ? 4. A block of metal of mass 100og is heated to 100 " C.It is then immersed in 100g of water at 0 . C in a calorimeter of mass 50 g and specific heat is 0.2. If the final temperature of the Mixture is 70 " C, What is the specific heat of the metal.? 5. Four hundred grams of aluminum at 100 * C is dropped into 100 g of water at 20 * C contained in a copper calorimeter of mass 80 g. What is the final temperature of the mixture? 6. If 5 kg of water freezes at 0" C, how many kilocalories of heat are liberated ? 7. How many calories of heat are needed to vaporize 500g of water at 100 . C ? 8.
