Question

A PENDULUM OF LENGTH L SWINGS FROM REST TO REST N TIMES IN ONE SECOND THE VALUE OF ACCELERATION DUE TO GRAVITY IS

PLEASE ITS URGENT!!

Answer 1

Answer:

the acceleration due to gravity is na

f=mg

=na

Answer 2

The acceleration due to gravity is derived as below:

• As we the time period T=2π√$\frac{l}{g}$.
• Where l is the length of the pendulum and g is the acceleration
• Frequency f=n/2=T=2/n

• 2/n=2π√$\frac{l}{g}$  
• Squaring both sides
• g=n²π²l
• That is the required acceleration
• The formula we get tell us about that the acceleration due to gravity is n times the length of the pendulum.
• They are square form.
• It tells that as the length of pendulum increases the effect of gravity or the acceleration of the body will goes on increasing.
