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

pls reply to these questions:

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 :)
