A block is kept on a frictionless inclined surface
Asked by admin @ in Physics viewed by 290 People
A block is kept on a frictionless inclined plane of inclination alpha, it is given acceleration a to keep the block stationary, then a is equal to
Answered by admin @
The incline is given an acceleration a. Acceleration of the block is to the right. Pseudo acceleration a acts on block to the left. Equate resolved parts of a and g along incline.
Therefore, macosα = mgsinα
or a = gtanα
