Question

please answer both questions. i don't have enough questions that i can post separately.i would be very thankful

1.A horizontal lever of length 5.5 m is pivoted at
its mid-point. A 5 N upward force (force with
upward vertical component) that makes an
angle of 70 deg with the horizontal-left is acting
at a point 0.3 m away from the left end of lever.
Calculate the torque acting on the lever. (1 point)

1. -13.29 N m
2. -11.511 N m
3. -4.152 N m
4. -6.863 N m
5. -9.437 N m

2.The center of gravity of two particles of masses
10.22 kg and 15.33 kg is located at the point ( 4, 3 ) m.
The 10.22 kg particle is located at the point ( -1, -4 ) m.
Find the location of the 15.33 kg particle. (1 point)

1. ( 13.496, 1.75 ) m
2. ( 7.333, 7.667 ) m
3. ( 2.923, 4.351 ) m
4. ( 13.496, 7.667 ) m
5. ( 7.333, 1.75 ) m
