Question

complete the following
(1) SI unit of torque is ___
(2) the sum of anticlockwise moment and clockwise moment in equilibrium is always ------
(3) centripetal force acts___ the centre along the____
(4) uniform circular motion is always ___ motion ​

Answer 1

Answer:

1.

SI unit of torque is N m and CGS unit is dyne cm

We know that 1 N=10

5

dyne and 1 m=100 cm

Thus

dyne cm

N m

=

dyne cm

10

5

dyne×100 cm

=10

7

2) the sum of anticlockwise moment and clockwise moment in equilibrium is always .....The algebraic sum of moments of all the forces acting on the body about the axis of rotation is zero, the body is in equilibrium.

3) the centripetal force is directed at right angles to the motion and also along the radius towards the center of the circular path

4) constant
