Question
Two particles start together from a point O and slide down along straight smooth inclined planes at 30o & 60o to the vertical & in the same vertical plane as in figure. The relative acceleration of second with respect to first will be (in magnitude & direction) as :
Options
A.
in the vertical direction
in the vertical directionB.
at 45o with vertical
at 45o with vertical C.
inclined at 60o to vertical
inclined at 60o to vertical D. inclined at 60o to vertical
inclined at 60o to vertical Solution
Resultant Acceleration =
tan α =
a = 30o
i.e. Resulting acceleration is in vertical direction.
