NEET Physics Vectors MCQ Question

Type: MCQ-diagram based-Easy-Class 11

Consider two vectors A\vec{A} and B\vec{B} in a plane, where A=3i^+4j^\vec{A} = 3\hat{i} + 4\hat{j} and B=1i^+2j^\vec{B} = 1\hat{i} + 2\hat{j}. If R\vec{R} is their resultant vector, how would you calculate the components RxR_x and RyR_y of R\vec{R}?

Question diagram
A

Add the corresponding components: Rx=3+1R_x = 3 + 1 and Ry=4+2R_y = 4 + 2.

B

Subtract the corresponding components: Rx=31R_x = 3 - 1 and Ry=42R_y = 4 - 2.

C

Multiply the corresponding components: Rx=3×1R_x = 3 \times 1 and Ry=4×2R_y = 4 \times 2.

D

Divide the corresponding components: Rx=3/1R_x = 3 / 1 and Ry=4/2R_y = 4 / 2.

Correct Answer

Option A

Detailed Explanation

The components of the resultant vector are the sums of the corresponding components of the vectors. This is derived from the properties of vector addition as given in the context.
