PRACTICE EXERCISE 4.12 Given that E = (3x + y) a, + xa, kV/m, find the work done in moving a-2 µC charge from (0, 5, 0) to (2, -1, 0) by taking the path (a) (0, 5, 0)(2, 5, 0) (2,-1, 0) (b) y = 5-3r Answer: (a) 12 mJ, (b) 12 mJ.

Given that a single point-like charge of -40 μC is fixed at the origin, calculate the work required to move a second 60 μC charge from r = 14 cm to r = 28 cm. Hint: pay attention to the signs. The work, W =  Units             .

can you solve this for value 10v thank you

4-) Between parallel plates when two conductive metal plates with an area of 0 cm are separated from each other by 10 mm, a-) Determine the capacitance of the empty condenser run C. b-) Find the maximum amount of load to carry when the capacity r is empty. e-) What is the capacity of the newly formed system and the maximum load the capacity run will carry when mica with a capacity re dielectric constant k 8 is placed? 2/3 Ç-)After loading the capacitance nC, when the external voltage is removed and mica and mm sine nylon (keaytan=3) are placed in 3mm, find the final V and C values. boşluk Sum 2mm
