यदि किसी कोण θ पर कार्य कर रहे दो बलों P और Q का परिणामी बल (resultant force), बल P के साथ α कोण बनाता है, तो निम्नलिखित में से कौन सा सत्य है?
- 1tan(α) = P sin(θ)P + Q sin(θ)
- 2tan(α) = Q sin(θ)P - Q sin(θ)
- 3tan(α) = Q sin(θ)P + Q cos(θ)✓
- 4tan(α) = P sin(θ)Q - P cos(θ)
सही उत्तर देखें
tan(α) = Q sin(θ)P + Q cos(θ)
