In the figure shown, a block of weight 10 N resting on a horizontal surface. The coefficient of static friction between the block and the surface μs = 0.4. If a horizontal force of 3 N is applied to the block, then the block will
1
Move over the surface with constant velocity
2
Move having accelerated motion over the surface
3
Not move
4
First it will move with a constant velocity for some time and then will have accelerated motion
