Question

62. A 1 kg block is being pushed against a wall by a force F = 75 N as shown in the figure. The coefficient of
friction is 0.25. The magnitude of acceleration of the block is
F
37°
(1) 10 m/s2
(2) 20 m/s2
(3) 5 m/s2
(4) None of these
of static friction between​

Answer 1

Answer:

Answer :

B

Solution :

As the upward force (45N) is greater than total downward force <br> (25N) hence, it has an upwards acceleration <br>
