2.In the shown figure all surfaces are rough.Block B is attached with a load of mass 6mthrough an ideal string passing over an idealpulley. Coefficient of friction is= 0.2 betweenall the surfaces. The correct option is:(A)friction force on C due to B is mg(B)friction force on A is zero(C)acceleration of block B is55(D)Load remains at rest.A3m6mB2mC11m
3.Two moles of an ideal monoatomic gas is takenthrough the process as shown in figure. The process isAB AdiabaticBC isobaricCD Linear relation between P and V.The net change in internal energy of the gas is:105BCADP(N/m2)V(m3)246
4.Two cars P and Q are moving with equal speed v = 40km/h on the two roads which are intersecting at 60°atpoint O as shown in the figure. Initially, PO is 80 km andQO is 50 km. The minimum separation between themwill be:
