A and B are two like parallel forces. A couple of moment H lies in the plane of A and B and is contained with them. The resultant of A and B after combining is displaced through a distance
AIEEE Solved Paper-2005
A)\[\frac{H}{A-B}\]
B) \[\frac{H}{2(A+B)}\]
C) \[\frac{H}{A+B}\]
D) \[\frac{2H}{A-B}\]
Correct Answer:
C
Solution :
Let the resultant of A and B be displaced by. Then, change in net momentum of A and B = applied momentum \[\therefore \]
