Homework Statement
A ball of mass 0.5 kg is attached to one end of a cord of unstretched length 0.6 whose other end is fixed . When a horizontal force of QN is applied to the ball in equilibrium , the cord increases by 10 percent and is inclined at β= arcsin3/5 to the downward vertical. Calculate the value of Q and the modulus of the cord
Homework Equations
T= λx/l where λ= modulus, x=extension and l=natural length
The Attempt at a Solution
I have tried to solve it by using the above eqn and using a right-angled triangle. I think my visualization of the problem is somewhat correct. But I don't think my approach is.
