Anil has a two-wheeler that weighs 120 kg. After completing his work, he used to park his vehicle in the regular parking place which is in connected to the ground with a ramp of inclination `45^(@)`. If the length of ramp is 1 m, then calculate the work done by Anil to park the vehicle anginst gravity. (`(g=10ms^(-2))`

A

10500 J

B

1005 J

C

1050 J

D

1500 J

Text Solution

Verified by Experts

The correct Answer is:
C
`AC=100cm,BC=BA,AC^(2)=AB^(2)+BC^(2)`
Since inclination is `45^(@),AB=BC`
Therefore, `AC^(2)=2AB^(2)`
`impliesAB=sqrt""(10000//2)`
The work done by Anil to park the vehicle against gravity `=mgh=mgxxAB" "("since "h=AB)`

`=120xx10xx0.7`
`=1,050J`
Hence, the correct option is (c).
