Question

$text A square plate hinged at end text A text , of side a and mass end text M text is placed in end text left parenthesis x minus z right parenthesis text plane. The plate is allowed end text text to fall upto end text left parenthesis x minus y right parenthesis text plane. Find its angular velocity. end text$ 4

${[\frac{3 g}{a \sqrt{2}}]}^{1 / 2}$
${[\frac{24 g}{7 a}]}^{1 / 2}$
${[\frac{12 g}{7 a}]}^{1 / 2}$
${[\frac{12 g}{7 \sqrt{2} a}]}^{1 / 2}$

The correct answer is: $open square brackets fraction numerator 3 g over denominator a square root of 2 end fraction close square brackets to the power of 1 divided by 2 end exponent$

Consider the following statements:
S₁ : Zero net torque on a body means always absence of rotational motion of the body.
S₂: A particle may have angular momentum even though the particle is not moving in a circle.
S₃: A ring of rolling without sliding on a fixed surface. the centripetal acceleration of each particle with respect to the centre of the ring is same.
State in order, whether $s subscript 1 comma s subscript 2 comma s subscript 3$ are true or false.

An equilateral triangle ABC formed a uniform wire has two small identical beads initially located at A. The triangle is set rotating about the vertical axis AO. Then the beads are released from rest simultaneously and allowed to slide down, one along Ab and other AC as shown. Neglecting frictional effects, the quantities that are conserved as beads slides down are:
