If effective length of a simple pendulum is equal to radius of earth (R), time period will be
A disc is suspended at a point R2 above its center, Find its period of oscillation.
A particle of charge -q & mass m moves in a circle of radius r around an infinitely long line charge having linear charge density +λ. Then time period will be--
The period T of a simple pendulum is T=2π√lg the maximum error in T due to possible errors upto 1% in l and 2.5% in g is
Periodic time (T) of a satellite revolving above Earth’s surface at a height equal to the radius of Earth (R), is g = 9.8m/s2
Time period T of a simple pendulum of length l is given by T=2π√lg. If the length is increased by 2%, then an approximate change in the time period is
