Question

If the angle of inclination is 90⁰ and acceleration due to gravity is 9.8 m/s²,find the acceleration experienced by the object.

please answer soon​

Answer 1

Acceleration due to gravity on the surface of moon, g  

′

=1.7ms  

−2

 

Acceleration due to gravity on the surface of earth, g=9.8ms  

−2

 

Time period of a simple pendulum on earth, T=3.5s

T=2π  

g

where,  

l is the length of the pendulum

∴l=

The length of pendulum remains constant

On moon's surface, time period, T
