Answer :
Answer:[tex]a_c=126.36 m/s^2[/tex]
Explanation:
Given
mass of object [tex]m=50 gm[/tex]
length of string [tex]L=80 cm[/tex]
Angular frequency [tex]\omega[/tex] will be [tex]\frac{4\pi}{1}[/tex] rad/s because it completing 2 complete circle in 1 sec
In rotation object turned [tex]2\pi[/tex] rad so for 2 rotation it will be [tex]4\pi [/tex]
centripetal acceleration is the inward acceleration experiences by an object when it moves in a circular path and it is given by
[tex]a_c=\omega ^2\times L[/tex]
[tex]a_c=(4\pi )^2\times 0.8[/tex]
[tex]a_c=126.36 m/s^2[/tex]
