Question

in a simple pendulum length increases by 4 and g increases by 2 then time period of simple pendulum

Answer 1

The time period of simple pendulam is increased by one percent.

You can find it out using the formula

$t \: = 2\pi \sqrt{ \frac{l}{g} }$

Answer 2

Answer:

let length of pendulum be 1

if it is increase by 4% then new length

will be =1l+4/100l=1.04%

same as g=1.02%

Explanation:

time period =1/2×1.04+1/2×1.02

ans=increase by 3%
