A solid cube of mass `2 kg` is placed on rough horizontal surface, in `xy-`plane as shown. The friction coefficient between the surface and the cube is `0.2`. An external force `3hat(i)+4hat(j)+5hat(k) N` is applied on the cube. (use `g = 10 m//s^(2)`)

A solid cube of mass 5 kg is placed on a rough horizontal surface, in xy-plane as shown. The friction coefficient between the surface and the cube is 0.4. An external force vecF=6hati+8hatj+20hatkN is applied on the cube. (use g=10(m)/(s^2) )

A constant horizontal force of 5N in magnitude is applied tangentially to the top most of a ring of mass 10 kg and radius 10 cm kept on a rough horizontal surface with coefficient of friction between surface and ring being 0.2. The friction force on the ring would be: (g = 10 m//s^(2))

A block of mass 5 kg is placed on a rough horizontal plane . The coefficients of stastic and kinetic friction between the block and surface are 0*5 and 0*3 respectively. A force of 100 N is applied at an angle 30^(@) with the horizontal as shown in the figure . The acceleration of the block will be [ g = 10 m//s^(2) ]
