Section-E: Subjective Type
Two wheels, each marked with a dot on its rim, are mounted side by side. Initially dots are aligned and wheels are at rest. One of the wheels is given a constant angular acceleration of (π/2) rad/sec2 and the other wheel is given a constant angular acceleration of (π/4) rad/sec2. Both accelerations are in same direction. Find the time (in s) after which the two dots will become aligned again for the first time.
