Questions  

 As shown in the below figure a body is projected up the plane, then the values of ax and ay are

a
−g cos β,  g tan β
b
−g cos β,  −g tan β
c
−g sin β,  −g cos β
d
−g sin β,  g cos β

detailed solution

Correct option is C

ax=−gsinθ=−gsinβ=acceleration due to gravity along the inclined plane ay=−gcosθ=−gcosβ=acceleration due to gravity along a line perpendicular to the inclined plane
