QNEET-2013-Ph-1581: NEET 2013 Physics - Class 11 NEET-2013-Ph-1581 Solution: The displacement 'x' (in meter) of a particle of mass 'm' (in…
The displacement 'x' (in meter) of a particle of mass 'm' (in kg) moving in one dimension under the action of a force is related to time 't' (in sec) by . The displacement of the particle when its velocity is zero will be 4 m 0 m (zero) 6 m 2 m
Multiple Choice Options
- A 4 m
- B 0 m (zero)
- C 6 m
- D 2 m
Step-by-Step Verified Solution
As t = x + 3
_ x = t _ 3
_ x = ( t _ 3 ) 2
Velocity, v = d x d t = 2( t _ 3 )
Velocity of the particle becomes zero, when
2( t _ 3 ) = 0 _ t = 3 s
At t = 3 s,
x = ( 3 _ 3 ) 2 = 0 m
