So you mean to say that it depends upon the significant figures present in the error involved in measuring the dependent physical quantities.

Thanks a lot for a prompt reply! So the governing rule is that uncertainty in the measurement should be reported to one significant figure .

Homework Statement I have doubt in calculating the permissible error. It goes as follows Measure of two quantities along with the precision of respective measuring instrument is A = 25.0 ± 0.5 m/s, B = 0.10 ± 0.01 s. A physical quantity C is calculated as C = A × B. What will be the value of...

I apologize for the error . I have corrected it below. STEP 2. \frac { ΔC } {C} = \Big ( {\frac { ΔA } {A} + \frac {Δ B} {B} } \Big ) = \Big ( {\frac { 0.5 } {25.0} + \frac {Δ0.01} {0.10} } \Big ) = 0.02 + 0.1 = 0.12 ΔC = 0.12 × 2.5 =0.30 m However, to what the significant...

Respected Sir With all due respect I did n't get you

Sir Could you please tell how to apply Law "X" to circuit given in figure 3.

Q. It is a classical problem in current electricity .The resistor cube consists of 12 resistors, each having a value r. What is the total resistance between the two diagonally opposite corners labeled A and H on the cube? Ans. The answer to this problem begins with that due to symmetry points E...
