expalin me errors how to claculate

Posted by Rishabh Mishra 7 years, 5 months ago

CBSE > Class 11 > Physics

Keshav Kabra 7 years, 5 months ago

For calculating errors first we have to find the average of the given digits or value...by An=A1+A2+A3+An/N .....this is the formula of average.. Then, for absolute error we have to substract all the given digits or value by the average answer....just like : An-A1, An-A2....... by this we find all absolute error...
