QAIPMT-2009-Ph-2172: NEET 2009 Physics - Class 11 AIPMT-2009-Ph-2172 Solution: Three concentric spherical shells have radii a b and c (a < b < …

Three concentric spherical shells have radii a b and c (a < b < c) and have surface charge densities σ−σ\sigma -\sigma and σ\sigma respectively. If VAVBV_A V_B and VCV_C denote the potentials of the three shells then for c = a + b we have VC=VB≠VAV_C = V_B \neq V_A VC≠VB≠VAV_C \neq V_B \neq V_A VC=VB=VAV_C = V_B = V_A VC=VA≠VBV_C = V_A \neq V_B

Multiple Choice Options

  • A 40 m s −- _ 1
  • B 25 m s −- _ 1
  • C 10 m s −- _ 1
  • D 20 m s −- _ 1

Step-by-Step Verified Solution

Relative velocity of the scooter with respect to the bus = (v s - 10) _ 1000 v s _ 10 = 100 _ v s = 20 m/s
