Engineering Mechanics
The frequency of oscillation of a compound pendulum is (where kG = Radius of gyration about the centroidal axis, and h = Distance between the point of suspension and C.G. of the body.)

2π. √(gh/kG² + h²)
1/2π. √(kG² + h²/gh)
1/2π. √(gh/kG² + h²)
2π. √(kG² + h²/gh)

Engineering Mechanics
According to Newton's first law of motion,

The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts
None of these
Everybody continues in its state of rest or of uniform motion, in a straight line, unless it is acted upon by some external force
To every action, there is always an equal and opposite reaction
