The Boolean expression \(\sim(p \vee q) \vee (\sim p \wedge q)\) is equivalent to :
Show Hint
- \(\sim q\)
- \(\sim p\)
- p
- q
The Correct Option is B
Solution and Explanation
The expression becomes \((\sim p\wedge\sim q)\vee(\sim p\wedge q)\).
Factor out \(\sim p\) (distributive law): \(\sim p\wedge(\sim q\vee q)\).
Since \(\sim q\vee q\) is a tautology (T), the expression equals \(\sim p\wedge T=\sim p\).
Answer: (2) \(\sim p\)

- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
