A physical quantity 'Q' is given by Q ` = (A^ 2 B^ ( 3//2 )) /( C ^ 4 D ^ (1//2 )) `. The percentage error in A, B, C, D, E are 1 %, 2 %, 4% , 2 % respectively . Calculate the minimum and maximum percentage errors in 'Q'

Text Solution

Verified by Experts

(a) Minimum error ` = [ ( 4xx 4 + 1 ) - ( 2 + 3 ) ] % = 12 % `
(b) Maximum error = ` ( 4 xx4 + 1 + 2 + 3 ) % = 22 % `
