Question

In determining momentum of a body errors in the measurem-
ents of mass displacement and time interval are
respectively . 2,3 and 6% The error in the momentun
will be the

(a) 1%
(6) 36%.
( 0%
(c) 11%​

Answer 1

mass=2

displacement=3

time =6/100=0.06

vecolity =distance/time

velocity=3/0.06

velocity=3×100/6

velocity=100/2

velocity (v)=50

momentum =P

formula P=MV

P=2×50

P=100units

in percent momentum P=100/100=1%

answer:(A) 1%

Answer 2

Answer:

as we know momentum is mass into velocity.

here dx/ft is given, not the velocity directly.

So , percentage error will be

1×2%+1×3%+1×6%

=11%
