Answer 2

20 N will be the force exerted.

Given: Rf = 40, a = 40/m

To find: Exerted force

Solution:

Simple pendulum:

A natural something used to measure heaviness is a machinelike composition that illustrates periodic motion. The natural device that tells time encompasses a limited jounce of bulk ‘m’ pensile by a thin series obtained to a platform at allure superior end of time L.The plain device that tells time is a machinelike order that sways or moves in an oscillatory motion.

This motion happens in a upright plane and is mainly compelled for one gravitational force. Interestingly, the hop namely postponed last of a fiber very light kind of we can reply it is even massless. The period of a natural device that tells time maybe fashioned widespread by growing the distance strand while communicable the measurements from the point of delay to the middle of the jounce.

Lets simplify it,

$a = 40/m\\F= m*40/2*m\\F= 20N$

So we get 20 N as force required.
