Each of the above three springs are identical (they have the same equilibrium length and spring constant $k$). They are fixed together as shown in the figure. What is the effective spring constant of the assembly?
Show Hint
- $k$
- $\frac{2}{3}k$
- $\frac{1}{2}k$
- $\frac{1}{3}k$
The Correct Option is B
Solution and Explanation
When springs are arranged in parallel, the effective spring constant is the sum of the individual spring constants. Therefore, the effective spring constant for this assembly is $\frac{2}{3}k$.

- The Hamiltonian for a one-dimensional system with mass \( m \), position \( q \), and momentum \( p \) is: \[ H(p, q) = \frac{p^2}{2m} + q^2 A(q) \] where \( A(q) \) is a real function of \( q \). If \[ m \frac{d^2 q}{dt^2} = -5q A(q), \] then \[ \frac{d A(q)}{d q} = n \frac{A(q)}{q}. \] The value of \( n \) (in integer) is:
