pls reply to these questions:
1: If there are more than one force F1;F2....... acting on a body, the total torque will be
Options:
a): Torque = r1.F1 + r2.F2 + …....
b): Torque = r1*F1
c): Torque = r1*F1 + r2*F2 +..........
d): None
2: If there are more than one force acting on the same particle then torque will be
Options:
a): Torque = r*(F1 + F2 +.....)
b): Torque = r*F
c): Torque = r.(F1 + F2 + ….....)
d): None
3: If different forces are acting at different points, is torque of each other equal to each other

For question 1, correct option is c because Torque is vector so cross product to be used.  
Same concept for question 2, option a is the correct answer.
For question 3, no, since force and r both are different, Torque isn’t always same. Could be same only when r1 x F1 = r2 x F2
 
I hope this helps :0 approve the answer if you like it :)
