Class 11PhysicsNewton's Laws of Motion and FrictionStatic and Limiting Friction and Minimum Force Required to Move
EasyIn the figure shown,a block of weight $10 \, N$ is resting on a horizontal surface. The coefficient of static friction between the block and the surface is ${\mu _s} = 0.4$. $A$ force of $3.5 \, N$ will keep the block in uniform motion,once it has been set in motion. If a horizontal force of $3 \, N$ is applied to the block,then the block will:
- AMove over the surface with constant velocity
- BMove having accelerated motion over the surface
- CNot move
- DFirst it will move with a constant velocity for some time and then will have accelerated motion
