Answer:
49 N
Explanation:
The diagram of the bar is obtained online and attached to this solution.
The free body diagram is also attached.
Since the weight of the bar acts at the middle of the bar, the torque due to the weight of the bar is given by
τ = mgx
where x = (L/2) cos 35° = 0.45 × cos 35° = 0.3686 m
τ = (7)(9.8)(0.3686) = 25.29 Nm
The force acting on pin A = torque ÷ (length × sin 35°) = 25.29 ÷ (0.9 × sin 35°)
= 25.29 ÷ 0.5162 = 48.99 N = 49 N

Yes because the mouse was moving with kts kwn force.
I think its A as in density
