A physical quantity P is described by the relation P= a^1/2 b^2 c^3 d^-4 . If the relative error in the measurement of a,b,c and d respectively are 2% , 1%, 3%, 5% then the relative error in P will be? (a) 8% (b) 12% (c) 32% (d) 25% Share with your friends Share 4 Vijay Shankar Yadav answered this Dear Student, Given formula is P=a12b2c3d-4-------1 for maximum error in P ∆PP×100=12∆aa×100+2∆bb×100+3∆cc×100+4∆dd×100 =12×2+2×1+3×3+4×5=3200 option c is correct 12 View Full Answer
