Dear student ....Base angle is always taken as cos ,it does not matter whether the line is vertical or horizontal .Here , base angle is on vertical that is why they took vertical component as 4cos 60 and horizontal as 4sin 60....With Regards ....Mahima....(askIITians Forum Expert)

Dear Student,
Please find below the solution to your problem.
As external torque is zero just apply conservation of angular momentum.
I1W1 = I2W2.
So (MR²/2)w0 = (MR²/2 + mR²)w.
So new w = Mw0/(M+2m).
Thanks and Regards

In viewing through a magnifying glass, one usually positions one's eyes very close to the lens. Does angular magnification change if the eye is moved back?

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
