6. 7. Light from a point source in air falls on a spherical glass surface. (n=1.5 and radius of curvature = 20 cm) The distance of the light source from the glass surface is 140 cm. At what position the image is formed from the glass surface? (1) At a distance of 100 cm in the direction of incident light. (2) At a distance of 33.33 cm in the direction of incident light. (3) At a distance of 33.33 cm in opposite to the direction of incident light. (4) At a distance of 84 cm in the direction of incident light. If the focal length of objective lens is increased, then magnifying power of (1) microscope will increase but that of telescope decrease. (2) microscope and telescope both will increase. (3) microscope and telescope both will decrease. (4) microscope will decrease but that of telescope increase. 8. Choose wrong statement for a conductor under electrostatic condition: (1) Electric field inside a conductor is zero. (2) Electric potential is constant throughout the volume of conductor. (3) Electric field at the surface of conductor is normal to the surface. (4) The total charge reside inside the conductor. 9. Figure given below shows four arrangements of charged particles. All are at the same distance from the origin rank. The situations according to net electric potential (V1, V2, V3 and V4) at the origin, most positive first. 2q -29 V -99 -3q V -29 -29 V-29 +29 39 69 (1) V>V2>V3>V4 (2) V>V>V3 V4 (3) V>V>V > V3 (4) V>V>V3>V 10. A parallel plate capacitor has a uniform electric field E in the space between the plates. If the distance between the plates is d and area of each plate is A, the energy stored in the capacitor is (1) E Ad (2) E Ad 2% 1% EA E A (3) 2 d (4) d
