Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 1 · difficulty 2/5
A glass rod acquires a positive charge of 3.2 × 10⁻⁹ C when rubbed with silk cloth. The number of electrons transferred from the glass rod to the silk cloth is:
A. 1.6 × 10¹⁰
B. 3.2 × 10¹⁰
C. 2.0 × 10¹⁰
D. 2.0 × 10⁹
Example 2 · difficulty 3/5
Two point charges +q and +4q are fixed at points A and B respectively, a distance L apart. A third point charge is placed on the line joining A and B such that the net force on it is zero. Its distance from A is:
A. L/2
B. L/3
C. 2L/3
D. L/4
Example 3 · difficulty 1/5
Which of the following statements about electrostatic field lines is INCORRECT?
A. They begin on positive charges and end on negative charges
B. Two field lines never intersect each other
C. The tangent drawn at a point on a line gives the direction of the electric field at that point
D. They form continuous closed loops in an electrostatic field
The evidence-first practice loop
1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
2. Attempt closed-bookExpose the concept or execution gap before rereading.
3. Repair and returnClassify the miss and re-practice after a delay.
