{TABULATE}
[UNDER REFLECTION OF LIGHT BY PLANE SURFACE]
(i) Forms an upright image always.
(ii) Image formed when light is reflected is always the same size as object.
[UNDER REFLECTION OF LIGHT BY CURVED SURFACE]
(i) Image formed by by curved mirror can be inverted or upright image formed.
(ii) Image formed depends on where the object is placed.
(2bii)
Angle about a point = 360°.
Angle between mirror = 360° – 320° = 40°.
No. of images formed by an inclined mirror = 360/∅ – 1,
Therefore, 360/40-1,
Therefore, 9 – 1 = 8.
Therefore, Number of images = 8 images.
(3bi) The possible cause of a one sided deflection of the galvanometer can be because the potential difference between the ends of the potentiometer wire or the E.M.F. of the cell connected in the main circuit may not be greater than the E.M.F. of the cells whose E.M.F. are to be compared.
OR
The positive terminals of the cells and the battery used, the circuit might not be connected to the same end of the potentiometer wire.
CORRECTION: In such a case we will ensure if all connections are tight and connecting wire are not broken.
(3bii) Parallel ——> Voltage remains
(1bii)
Weight in Air = 2.9N
Weight in water= 1.3N
Relative Density= ?
Relative Density = Weight in Air/ Change in weight of water
R.D = 2.9/(2.9 – 1.3)
= 2.9/1.6 = 1.8125
Relative Density = 1.813

The positive terminal of the cells and the battery used the circuit might not be connected potentiometer wire
Correction: In such case we will ensure if all connections are tight and connecting wire are not broken
(3bii)
Parallel —> Voltage remains the same
For series —> Current remains the same
