A block of mass m is stationary with respect to a rough wedge as shown

1.	A block of mass m is stationary with respect to a rough wedge as shown in figure. Starting from rest in time t.(Given that m=1 kg,θ=30∘,a=2 m/s2,t=4 s)Match Column I with column IIColumn-IColumn-II(a) Work done on block by gravity(p) 144 J(b) Work done on block by normal reaction(q) 32 J(c) Work done on block by friction(r) 56 J(d) Work done on block by all the forces(s) 48 J(t) None
Answer» A block of mass $m$ is stationary with respect to a rough wedge as shown in figure. Starting from rest in time $t$ . (Given that $m = 1 kg, θ = 30^{\circ}, a = 2 {m/s}^{2}, t = 4 s$ ) Match Column $I$ with column $I I$ $\begin{matrix} Column-I & Column-II (a) Work done on block by gravity & (p) 144 J (b) Work done on block by normal reaction & (q) 32 J (c) Work done on block by friction & (r) 56 J (d) Work done on block by all the forces & (s) 48 J (t) None \end{matrix}$
