1.
What is the purpose of the end correction in the resonance tube experiment?
2.
Which principle does the Wheatstone bridge (and hence metre bridge) operate on?
3.
In Stokes' law, the viscous drag force on a sphere of radius r moving at velocity v is:
4.
The focal length of a concave mirror determined by the u-v method for multiple object positions is plotted. Which graph will give the focal length most accurately?
5.
A convex lens (f = 20 cm) is used to find its focal length by u-v method. Object at u = −60 cm. If measurement of v has error ±0.5 cm, and v_measured = 30 cm, the percentage error in f is approximately:
