If so what is its acceleration? O No the block will not move. We have not overcome static friction 0 Yes the block will move in the positive x-direction (to the right) with an acceleration of 4.14 rule2 0 Yes the block will move in the positive xdirecticn (to the right) with an acceleration of 0.5 mlsz 0 Yes the block will move in the negative x-direction (to the left) with an acceleration of 4.14 rrI/s2 QUESTION 25 What happens to the magnitude of normal force as you decrease the angle of inclination? O Decreases O Remains same 0 First increases and then decreases .7 O Increases 0 Normal force is Independent of angle of Inclination QUESTION 26 What happens to the magnitude of violet force as you increase the angle of inclination? QUESTION 21 O Incmases For which angle are the normal and the violet force equal? (degree) 0 Decreases 7 0 First increases and then decreases O Remains same 0 Normal force Is Independent of angle of Inclination
