JEE Main Physics Test- 12 - Question 23

A block of mass m is at rest on an inclined surface having a coefficient of friction as shown in the figure. The horizontal acceleration which shouldbe given to the inclined plane, that the force of friction between the block and the plane become zero, is

Detailed Solution for JEE Main Physics Test- 12 - Question 23

JEE Main Physics Test- 12 - Question 24

A block of weight 5N is pushed against a vertical wall by a force 12 N. The coefficient of friction between the wall and block is 0.6. The magnitude of the force exerted by the wall on the block is

Detailed Solution for JEE Main Physics Test- 12 - Question 24

Due to normal reaction a force of 12N acts towards left.

and also as block is at rest frictional force must balance the weight. therefore frictional force is 5N in upward direction.

hence the two forces are perpendicular

so resultant = √(12*12 + 5*5 ) = 13N
