NEET Physics (general) Match the Following Question
Type: Match the Following-match the column-Hard-Class 11
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Work done by net force | (i) Change in kinetic energy |
| (b) Kinetic energy of a bullet | (ii) mv²/2 |
| (c) Initial kinetic energy | (iii) 0.1×initial energy |
| (d) Emergent speed of bullet | (iv) 63.2 m/s |
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-iii, b-iv, c-i, d-ii
D
a-iv, b-iii, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
The work done by the net force on an object is equal to the change in kinetic energy of that object, which corresponds to option (i). The kinetic energy of a bullet is calculated as mv²/2 (option ii). Initially, the bullet has a certain kinetic energy, and after passing through a barrier, it retains only 10% of that energy, confirming option (iii). The emergent speed calculated is 63.2 m/s (option iv).
