The figure shows a smooth fixed wedge on which a block of mass m is kept and released, then which of the following(s) are true. ( →a= acceleration of block and N is the contact force between the block and the wedge)

Options:(select one or more)

Answer:

B, C, D

Solution:

[0pt] [RT-2\_11th(P) Paper-1\_03-07-16]

$N = m g cos θ a = g sin θ or a = \frac{N sin θ}{m} \hat{i} + \frac{( N cos θ - m g ) j ^}{m} a = g sin θ cos \hat{i} + g sin^{2} θ (- \hat{j})$

At $t = 0$ , a force $F = at^{2}$ is applied to a small body of mass m at an angle $α$ resting on a smooth horizontal
