Question

1. The kinetic energy of a particle depends on the
square of speed of the particle. If error in
measurement of speed is 30%, the error in the
measurement of kinetic energy will be
(1) 30%
(2) 60%
(3) 69%
(4) 15%​

Answer 1

Answer:

the correct answer is option (2) 60%

error = v²

so there is error of 60%
