Approved Tutor Answer15 Years agomagnitude[A-B] = magnitude[A+B]
squaring both sides
A2 + B2 - 2A.B = A2 + B2 + 2A.B
A.B = 0
A.B = ABCOS@ so
cos@ = 0
@ = pi/2
therefore angel bw A,B is 90o ...
approve if u like my ans

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
