Q3.2: NCERT Physics - Part 1 MOTION IN A PLANE 3.2 Solution: Pick out the two scalar quantities in the following list:…
⚠️ Common Exam Traps & Conceptual Pitfalls
Students frequently mistake quantities defined by dot products (e.g., work = $\,\vec F\cdot\vec d,$) as vectors and assume current has a direction like charge flow; remember that a dot product yields a scalar and electric current is treated as a magnitude‑only quantity in circuit analysis.
Pick out the two scalar quantities in the following list: force, angular momentum, work, current, linear momentum, electric field, average velocity, magnetic moment, relative velocity.
Step-by-Step Verified Solution
**Answer:** Work and current.
**Step-by-Step Explanation:**
Work is the dot product of force and displacement, which is a scalar. Current has magnitude only; its direction is not considered for circuit analysis. [citation:1][citation:12]
