Two thin-walled concentric conducting spheres of radii 5.0 cm and 10 cm have a potential difference of 100 V between them.
 
  (k = 1/40 = 8.99  109 N  m2/C2)
  (a) What is the capacitance of this combination?
  (b) What is the charge carried by each sphere?

Question 2

Blocks A and B of masses 10 kg and 7 kg, respectively, are connected by a rope, which passes over a light frictionless pulley, as shown. The horizontal surface is rough. The coefficients of static and kinetic friction are 0.40 and 0.20, respectively.
 
  External forces P and Q act on block B, as shown. In Figure 5.20, force P equals 28 N. The maximum value of force Q, for which the system remains at rest is closest to: A) 140 N
  B) 120 N
  C) 98 N
  D) 110 N
  E) 130 N
