Dear Abhingya

x=at², y=bt

for locus of particle you need to replace t from the above equation

x=a (y/b)²

y²=b²x/a

clearly it is a equation of parabola

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
