Question

A physical quantity p is given by p =a^2√b/c and the percentage errors in the measurment

Answer 1

Answer:

7%

P=A^2√B / C

ΔP/ P = 2(ΔA/A) + 1/2(ΔB/B) + ΔC / C

Substituting,

ΔA / A x 100 = 1

--> ΔA / A = 0.01

ΔB / B x 100 = 2

--> ΔB / B = 0.02

ΔC / C x 100 = 4

--> ΔC / C = 0.04

ΔP / P = 2(0.01) + 0.01 + 0.04

= 0.07

ΔP/P x 100 = 0.07 x 100

= 7%
