Question

The error in the measurements of mass and volume
of a solid are 5% and 2% respectively. The maximum
percentage error in the measurement of its density
will be :
(a) 10 (b) 25 (c) 7 (d) 3.
(full explanation?)​

Answer 1

Explanation:

First, D= M/V

here , M = 5%

V = 2%

Now according to formula

D×100/100 = M×100/100 + V×100/100

= 5×100/100 + 2×100/100

= 5 + 2

Hope this will help you ..

= 7

Answer 2

Answer:

c) 7

Explanation:

c) 7 Is the correct answer of this question .

Given : The error in the measurements of mass and volume

of a solid are 5 % and 2 % respectively. The maximum

percentage error in the measurement of its density

To solve : The error in the measurements of mass and volume

of a solid are 5 % and 2 % respectively. The maximum

percentage error in the measurement of its density will be :

Solution :

First , D= M / V

here , M = 5 %

V = 2 %

Now according to formula

D × 1 0 0 /1 0 0 = M × 1 0 0 / 1 0 0 + V × 1 0 0 / 1 0 0

= 5 × 1 0 0 /1 0 0 + 2 × 1 0 0 / 1 0 0

= 5 + 2

= 7
