Question

actual length of a rope is 22.5 but it is wrongly measured as 21.6 M find the percentage error​

Answer 1

Answer:

Answer

Error measured =22.5−21.6=0.9m

So the percentage of error =  

percentage error = | actual reading - wrong reading | / actual reading * 100%

here in this question,

percentage error= | 21.6 - 22.5 | / 22.5 * 100%

= 4%

So there is a 4% error.
