IF there is a positive error of 50% in the measurement of velocity of a body, then the error in the measurement of kinetic energy is
a
25%
b
50%
c
100%
d
125%
detailed solution
Correct option is D
Kinetic energy E = 12mv2∴ △EE×100 = V'2-v2v2×100 = [(1.5)2-1]×100∴△EE×100 = 125%Talk to our academic expert!
