A mass (M1 = 5.0 kg) is connected by a light cord to a mass (M2 = 4.0 kg) which slides on a smooth surface, as shown in the figure. The pulley (radius = 0.20 m) rotates about a frictionless axle. The acceleration of M2 is 3.5 m/s2. What is the rotational inertia of the pulley?
 
 
 
   
  a.
  0.29 kgm2
   
  b.
  0.42 kgm2
   
  c.
  0.20 kgm2
   
  d.
  0.62 kgm2
   
  e.
  0.60 kgm2

Question 2

An ideal solenoid of radius a has n turns per unit length and current I. The magnetic flux B through any area completely inside the solenoid, centered on the solenoid axis but at a 45 angle to the axis, so that it touches the inside of the solenoid, as shown below, is
 
   


   
  a.
  .
   
  b.

Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
