Dear student
Vac = 15 V
R1+R2 = 30 ohms
R3+R4 = 50 ohm
Current at node b = 0.5 amp
Current at node d = 0.3 amp
Vb = Vac - Vr1 = 15 - (10/30)*15= 10
Vd = Vac - Vr2 = 15 - (30/50)*15 = 6v
Vbd = 4 v
Regards

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
