Equation of the plane such that foot of altitude drawnfrom - 1, 1, 1) to the plane has thecoordinate(3, -2, -1), is:

​

Answer 1

Step-by-step explanation:

A thin uniform circular disc of mass M and radius Ris rotating in a horizontal

plane about an axis perpendicular to the plane at an angular velocity o. Another disc

of mass M/3 but same radius is placed gently on the first disc coaxially. The angular

velocity of the system now is

A)4omega /3

B) omega

C)3omega/4

D)3omega/8
