A manufacturer produces computers data storage floppies at the rate of x units per week and his total cost of production and marketing is C (x) = (x^(3)/(3)- 10 x^(2)+ 15 x +30) . Find the slope of average cost .

Three students use a computer for a total of 3 hours. If the first students uses the computer 28% of the total time, and the second student uses the computer 52% of the total time, how many minutes does the third student use the computer?

Three concentric conducting spherical shells of radii R, 2R and 3R carry charges Q, - 2Q and 3Q , respectively. a. Find the electric potential at r=R and r=3R where r is the radial distance from the centre . b. Compute the electric field at r=5/2R c. Compute the total electrostatic energy stored in the system. The inner shell is now connected to the external one by a conducting wire, passing through a very small hole in the middle shell. d. Compute the charges on the spheres of radii R and 3R . e. Compute the electric field at r=5/2R
