T is inversely proportional to sqrt(g) therefore it is directly proportional to distance from centre of earth(for points on or above earth's surface). g=GM/R²T1/T2 =(R/(R+K)) R is radius of earth

T is proportional to 1/[(g)^1/2]

t1/t2=[g'/g]^1/2

g=GM/R^2

g'=GM/(R+K)^2

t1/t2=[R/(R+K)]

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
