Question
A body kept on a smooth inclined plane inclination 1 in x will remain stationary relative to the inclined plane is given a horizontal acceleration equal to :-
Options
A.
B.
g
gC.
D.
Solution
sin θ 
tan θ 
For body N cos θ = mg
N sin θ = ma
⇒ a = g tan θ
tan θ For body N cos θ = mg
N sin θ = ma
⇒ a = g tan θ
