146228 A block of mass \(10 \mathrm{~kg}\) is placed on a rough horizontal surface whose coefficient of friction is 0.5 . If a horizontal force of \(100 \mathrm{~N}\) is applied on it, then acceleration of block will be:

146229 A block of mass \(2 \mathrm{~kg}\) rests on a plane inclined at an angle of \(30^{\circ}\) with the horizontal. The coefficient of friction between the block and surface is 0.7 . The frictional force acting on the block is :

146230 A block of mass \(0.1 \mathrm{~kg}\) is held against a wall by applying a horizontal force of \(5 \mathrm{~N}\) on it. If \(\mu_{\mathrm{s}}\) is between the wall and the block is 0.5 , the magnitude of the frictional force acting on the block is

146231 A uniform chain of length \(L\) is lying partly on a table, the remaining part hanging down from the edge of the table. If the coefficient of friction between the chain and the table is 0.5 , what is the minimum length of the chain that should lie on the table, to prevent the chain from slipping down to the ground?

146234 Assertion: Angle of repose is equal to the angle of limiting friction.
Reason: When the body is just at the point of motion, the force of friction in this stage is called limiting friction.
