Question

in measurements of kinetic energy if the percentage error in mass and velocity are 1% and 2% respectively . the maximum percentage error is​

Answer 1

Answer:

Maximum percentage error is 8%.

Given that the percentage error in the measurement of mass to as 2% and the speed to be as 3%

We have to find the maximum percentage error for the kinetic energy.

That is,

Mass is denoted by m=2%,

Speed is denoted by v=3%

For kinetic energy we have

We have

Now by substituting the values of m and v in the above expression,

= 2+2 x 3

= 2+6

=8

Hence maximum percentage error is to be 8%
