Q1:

A disturbing mass m1 attached to the rotating shaft may be balanced by a single mass m2 attached in the same plane of rotation as that of m1, such that (where r1 and r2 are the radii of rotation of m1 and m2 respectively)

A m1r2 = m2r1

B m1r1 = m2r2

C m1m2 = r1r2

D none of these

ANS:B - m1r1 = m2r2
