What is the magnitude of vector a = 3i + 4j?
Vector a = 3i + 4j की magnitude क्या है?
Show answer and explanation
Correct Answer
C. √25
ExplanationStep 1: For vector magnitude, add the squares of components. Step 2: |a| = √(3^2 + 4^2) = √25. Step 3: Magnitude is the square root of the sum of squares.
Step 1: Vector की magnitude के लिए components के squares जोड़ें। Step 2: |a| = √(3^2 + 4^2) = √25। Step 3: Magnitude हमेशा square root of sum of squares होती है।
