Respuesta :
For ideal pendulum we will say
The string in that case must be massless and in-extensible
Frictional forces must be zero
there should not be any contact surface of pendulum
Whole mass of pendulum must be concentrated at the center
so above all conditions of pendulum we will say time period is given as
[tex]T = 2\pi \sqrt{\frac{L}{g}}[/tex]
now the correct answer will be
gravitational force
tension
inertia
Gravitational, tension and inertia have the ideal pendulum experience.
Answer: Option B,E,F
Explanation:
Ideal pendulum is an object or ball suspended by a thread which will freely vibrate from left to ring and then from right to left and this process repeats continuously.
The rod is suspended by a thread which represents tension, since it is always confined within its region, it is due to inertia, and gravity is the main force acting on all objects in the earth.
