sorry
but i can solve only first question according to HOMEWORKLIB RULES and
regulations.
Example: Charge q1-3.0 HC is at (4.0 cm, 4.0 cm), charge q2 +1.0 uC is at (0.0 cm, 0.0 cm), and charge q3 +6,0 HC is at (-5.0 cm, 0.0 cm). Find net force on the third charge. (Solution: F3-9.2 N, e,-131.90)
Q2: You add Mg to a beaker containing HC(ag) and a gas is produced. Explain, chemically, what is happening and write a balanced cquation for the reaction, including how many electrons are transferred. How could you hamess the reaction to do useful work?
Plz explain why. Thank you
6. E Go A plate carries a charge of -3.0 HC, while a rod carries a charge of +2.0 uC. How many electrons must be transferred from the plate to the rod, so that both objects have the same charge? 7. -HINT Water has a mass per mole of 18.0 g/mol, and each water mo- lecule (H,0) has 10 electrons. (a) How many electrons are there in one liter (1.00x 10-m') of water? (b) What...

In a vacuum, two particles have charges of q1 and q2, where q1+3.9 HC. They are separated by a distance of 0.27 m, and particle 1 experiences an attractive force of 2.8 N. What is q2 (magnitude and sign)? magnitude 5.75E-7XC sign I negative
Two charges, Q13.30 HC, and Q2 5.10 HC are located at points (0,-2.50 cm) and (0,+2.50 cm), as shown in the figure What is the magnitude of the electric field at point P, located at (5.00 cm, 0), due to Q1 afone? 23.76 10"6 N/C The electric field at position P due to charge 01 is not influenced by charge Q2. Therefore, ignore charge Q2 and apply Coulomb's Lavw Remember to convert all units to the SI unit system Submit...
