Approved Tutor Answer10 Years agoFocal Length: The distance of principle focus from optic center is called focal length of a
concave lens.
Radius of Curvature: The radius of the sphere of which the curved surface of the lens forms
a part is called the radius of curvature of a concave lens. A concave lens has two radii of
curvatures.

. Because of the rotation of the earth, a plumb bob may not hang exactly along the direction of
the earth’s gravitational pull (its weight) but deviates slightly from this direction. Calculate the
deviation (a) at 40 latitude, (b) at the poles, and (c) at the equator

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
