Question

Two fixed frictionless inclined planes making an angle $30 to the power of ring operator end exponent$ and $60 to the power of ring operator end exponent$ with the vertical are shown in the figure. Two blocks A and B are placed on the two planes. What is the relative vertical acceleration of A with respect to B ?

4.9 ${m s}^{- 2}$ in vertical direction
4.9 ${m s}^{- 2}$ in horizontal direction
9.8 ${m s}^{- 2}$ in vertical direction
Zero

The correct answer is: 4.9 $m s to the power of negative 2 end exponent$ in vertical direction
