Alevel Physics
Guys I need urgent help in this question,
There are five repeats of the same acceleration test and it took the following readings: 0.87s, 0.89s, 0.65s, 0.76s, 0.77s
Which of these is the correct percentage error for this set of time readings?
a.0.12%
b.0.15%
c.15%
d.30%
please leave a method to how ur working got the answer

What have you tried? Do you know how to find the uncertainty?

Don't double post the same question. Don't just expect the helper to give you the solution without you putting in the effort of attempting the question.

I know how to find uncertainty but this question asks for percentage error,

In A level, you can take percentage error as percentage uncertainty unless you are told otherwise.

how can i possibly find it? average? taking half range? i cant get the ans

Show your working

Show your working
for range 0.89-0.65/2
Original post by zzayn
for range 0.89-0.65/2
for average all the values divided by 5
Original post by zzayn
for range 0.89-0.65/2
The is NOT range. This is the uncertainty.

It is not helpful. Show your working instead of keep saying not getting the answer, We can help as long as you provide useful info.

It can be a simple arithmetic mistake(s) and if you do not show your working, it is difficult for us to identify them.

bro why can't u jus solve the question and tell me the answer? I have provided you the details with the question??? stop asking me to provide working? i cant solve it

Dude, similar question, why can’t you post your working as you mentioned the “correct method” below.
Original post by zzayn
for range (0.89-0.65)/2
Original post by zzayn
for average all the values divided by 5
It is not that you cannot do from what I am seeing. It is just that you are expecting others to provide a solution/answer. This is NOT "a doing homework for me" forum but a helping or guiding forum.

You are just lazy. Equivalently, you are also wasting my time to help. This is my last post for this thread.
Original post by zzayn
for uncertainty (0.89-0.65)/2
What is your answer? Don’t tell me you cannot press the calculator.
Original post by zzayn
for average all the values divided by 5
Again what is your answer? Don’t tell me you cannot get an answer or expect others to do for you.
The above 2 simple tasks are already showing how lazy are you.

In A level, you can take percentage error as percentage uncertainty unless you are told otherwise.
Percentage error = (uncertainty/average)*100%
