1. ### Calculation of permissible error in physical quantity

So you mean to say that it depends upon the significant figures present in the error involved in measuring the dependent physical quantities.
2. ### Calculation of permissible error in physical quantity

Thanks a lot for a prompt reply!!!! So the governing rule is that uncertainty in the measurement should be reported to one significant figure .
3. ### Calculation of permissible error in physical quantity

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...
4. ### Calculation of permissible error in physical quantity

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...

7. ### 12 Resistor cube problem

Sir Could you please tell how to apply Law "X" to circuit given in figure 3.
8. ### 12 Resistor cube problem

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...
