The dimensions [ML^{-2}A^{-2}] belong to the: (1) magnetic permeability (2) electric permittivity (3) magnetic flux (4) self inductance 3. A biconvex lens has radii of curvature, 20 cm each. If the refractive index of the material of the lens is 1.5, the power of the lens is: (1) +5D (2) infinity (3) +2D (4) +20D.
Understand the Problem
The question is examining multiple physics problems typically found in the NEET exam, covering topics such as dimensions, gas processes, lens power, and the radius of gyration.
Answer
1. Magnetic permeability 3. +5D
- Magnetic permeability 3. +5D
Answer for screen readers
- Magnetic permeability 3. +5D
More Information
Magnetic permeability is a measure of a material's ability to support the formation of a magnetic field within itself. A lens with equal radii of curvature each 20 cm, and a refractive index of 1.5, has a power of +5D derived from the standard lensmaker's formula.
Tips
Ensure the correct substitution of radii with signs in lensmaker's formula. Remember that positive curvature means convex surfaces.
