block moves down the plane with constant velocity it means net force is zero...

force due to friction (f) = mgsin A (A is the angle of plane)

net retardation force when body is projected upward is ( f+ mgsin A)

f = mgsin A so

net retardation force = 2mgsin A

ma = mgsin A

a(retardation) = 2gsin A .............1

V² = U² - 2aS

finally velocity becomes 0 so

V² = 2aS

S = V²/2a

=V²/4gsin A

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
