A uniform but time varying magnetic field ( B ( t ) ) exists in a cylindrical region of radius ( ) and is directed into the plane of the paper, as shown in fig. The magnetic field decreases at a constant rate inside the region. If (r ) is the distance from the axis of the cylindrical region then match column I to column II. ( array |c|l|c|l| & Column-I & & Column-II I. & Induced electric field & a. & 0 to 1 & at poin

Options

  1. AI -a, II - d, III - d, IV - a
  2. BI -d , II -a , III -c , IV -a
  3. CI (-a ), II (-b ), III (-c ), IV (-d )
  4. DI - a, II - a, III - c, IV - c

Correct answer

D. I - a, II - a, III - c, IV - c

Step-by-step solution

Matching with Option (4) (I-a, II-a, II-c, IV-c): - I. Induced electric field at point A : The option states ' a ' (0 to 1). This is consistent with a field that starts at 0 and increases linearly inside. - II. Induced electric field at point B: The option states ' a ' (0 to 1). This implies a range for the field outside. - III. Force on an electron at point A : The option states ' c ' (0 to 4). This reflects the force being proportional to the electric field inside. - IV. Force on an electron at point B: The optio
