Kinematics Question 33

Question: Three concurrent forces of the same magnitude are in equilibrium. What is the angle between the forces? Also name the triangle formed by the forces as sides [JIPMER 2000]

Options:

A) 60 equilateral triangle

B) 120 equilateral triangle

C) 120 , 30 , 30 an isosceles triangle

D) 120 an obtuse angled triangle

Show Answer

Answer:

Correct Answer: A

Solution:

In N forces of equal magnitude works on a single point and their resultant is zero then angle between any two forces is given θ=360N

=3603=120 If these three vectors are represented by three sides of triangle then they form equilateral triangle
