Question

The percentage errors in the measurement
of mass and length of the edge of a
cube are 3% and 2% respectively. The maximum
percentage error in the density would be:-​

Answer 1

Answer:

Explanation:

ERROR IN  MASS =  3%

ERROR IN LENGTH = 2%

ERROR IN DENSITY = ?

DENSITY = MASS / VOLUME       [ VOLUME = L*L*L]

DENSITY = M/ L³

DENSITY = ML^-3

ERROR IN DENSITY = 1* ERROR IN MASS+3*ERROR IN LENGTH

                                  = 1*3+3*2

                                  = 9%
