The effective length of a simple pendulum is the sum of the following three: length of string, radius of bob, and length of hook.In a simple pendulum experiment, the length of the string, as measured by a meter scale, is $92.0$cm. The radius of the bob combined with the length of the hook, as measured by a vernier callipers, is $2.15$cm. The effective length of the pendulum is

ANSWER

$94.2$cm

SOLUTION
Length of the string$=92.0㎝$
Radius of bob+length of hook$=2.15㎝$
Total length$=\left( 92.0+2.15 \right) ㎝$
$=94.15㎝$
Rounding off to first decimal place$=94.2㎝$
Hence, effective length$=94.2㎝$
