how did you guyz found the %uncertainty in k? (for physics) I think i did it wrong i took the uncertainty of meter rule becoz they said in the starting that we can measure the wavelength from the diameter of the inner circle and when i measured it was coming 2.51(the value in the table)... now God knows which is correct...

whoever lost 5-6 marks dont worry... jan 14 exams were kind of similar to these and the grade boundary for physics was pretty low for chem it was high though... i hope they are low this sessionIMG_20140516_140242.JPG IMG_20140516_140217.JPG

Talking about it will relieve no pain, it will just make you re-live the pain. What is lost is lost. Let's try to do well in our remaining papers and hope for the best!
