The distance traveled by pendulum, in one back-and-forth swing is 75.75 inches.
The period of pendulum can be calculated by
Where,
- period
- length = 12 inches
- gravitational acceleration =
Put the values,
Now, the angular displacement of the pendulum can be calculated by,
Where,
- amplitude
- angle =
- angular displacement =
= 2.866 m
Put the values and calculate for ,
Therefore, the distance traveled by pendulum, in one back-and-forth swing is 75.75 inches.
To know more about Amplitude of pendulum,
Answer:
F = 10 N
Explanation:
- Assuming that we can treat to both particles as point charges, the magnitude of the force that one charge exerts on the other, must obey Coulomb's Law.
- The expression for this force, applied to the charges +Q and +q, separated by a distance d, is as follows:
- If we replace +Q by +4Q, and d by 2*d, the new expression for the magnitude of the force is as follows:
- As it can be seen, the force will be as same as before making changes, so F= 10 N.
