Choose an option
Show full solutionCorrect option: A
Correct answer
A
Step-by-step explanation
Acceleration of vehicle down the incline will be
In the frame of the vehicle, we have to apply pseudo force. The Force diagram is shown in figure.
Component of along the inclined (i.e. ) will balance the pseudo force. Therefore,
Hence,.
