Question

The length of 2 rods are 15.2 +-0.2cm and 10.7+0.2cm .Find difference in length of 2 rods with the limits of error.

Answer 1

Given:

The length of 2 rods are 15.2 $\pm$ 0.2cm and 10.7 $\pm$ 0.2cm.

To find:

Difference in length of 2 rods with limits of error.

Calculation:

Difference between the length of the error will involve the subtraction of the lower value from the larger value.

$L = 15.2 - 10.7 = 4.5 \: cm$

Max error involved during calculating difference will be equal to sum of individual errors :

$\Delta L = \pm 0.2 \pm0.2 = \pm0.4$

So, net result is:

$\therefore \: L + \Delta L$

$= 4.5 \: \pm \: 0.4 \: cm$

So, final answer is:

$\boxed{ \sf{4.5 \: \pm \: 0.4 \: cm}}$
