Given :-
Length of the string of pendulum = 400 cm
To Find :-
The minimum velocity for the Bob to complete just one revolution.
Analysis :-
Here we are given with the length of the string of the pendulum.
In order to find the minimum velocity for the bob to complete just one revolution; substitute the values accordingly such that velocity is equal to root 5 into gravity into radius.
Solution :-
We know that,
- g = Gravity
- v = Velocity
- r = Radius
Using the formula,
Given that,
Gravity (g) = 10 m/s
Radius (r) = 400 cm
= 1 cm = 0.01 m
= 400/100
= 4 m
Substituting their values,
⇒ v = √5 × 10 × 4
⇒ v = √200
⇒ v = 14.14 m/s
Therefore, the minimum velocity for the Bob to complete just one revolution is 14.13 m/s.
