A circular disc is rotating with a varying speed u =(2t-4) m/s, where t is in second. An object is placed in the disc. The pseudo fore on the object is
is maximum at t = 2 sec.
is minimum at t = 2 sec
is zero at t = 2 sec
None of the above
Total acceleration of the disc aT2+aR2 and pseudo force depends on net acceleration.
aT=2 m/s2aR=u2/R at t =2sec u=0 aR=0
