In an experiment, four quantities a,b, c and d are measured with percentage error 1%, 2%, 3% and 4% respectively. Quantity P is calculated as follows:
P =Â , error in P is

• 14 %

• 10 %

• 7 %

• 4 %

A.

14 %

Here, P =Â
Therefore,

=Â
=Â
= 3 x1 + 2 x 2 + 3 +4Â

= 3 + 4 + 3 + 4

= 14 %

Here, P =Â
Therefore,

=Â
=Â
= 3 x1 + 2 x 2 + 3 +4Â

= 3 + 4 + 3 + 4

= 14 %
