kinetic energy of a satellite is x then what is the time period proportional to
1 Answer
Vikas TU
Kinetic enrergy for satellite is given as:
1/2mv^2 = x
now, v = wr
where w is the angular speed os satellite.
1/2*m*(wr)^2 = x
T ime Period, T = 2pi/w or w = 2pi/T
1/2*m*(2pi*r/T)^2 = x
or
T^2 = pi^2*r^2*m/x
or
x = pi^2*r^2*m/T^2
or
T^2 = C/x
T^2 is inversely proprtional to x.

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
