Title: A stupid but important question
Post by: vamsiaus on May 30, 2009, 05:36:52 pm

I have been doing trial exams for physics, and most of the time the answers I get are in some way; a little off the answers suggested in the solutions. For example if i get 2655N or something, the solutions has an answer that is like 2600 or 2650N. Although this maybe a very small error, do I lose marks for not getting the exact answer as what they have, or do the markers have a range for the solutions to accept.
Thanks.

No you won't lose marks.

there is a range in which they will accept. so ur answer probs won't get marked down but i may depend on the question as well. as sometimes the question may go to decimal places or ur answer will vary because of how many values u took it to and stuff.

Not as important as in Chemistry.  In Physics you're given some leeway with sign. figures - so long as you don't go crazy and put something along the lines of "2.23593446063469545324536 N", you'll be fine.
