NEETPhysicsElectrostatics
Column I gives certain situations in which a straight metallic wire of resistance R is used and Column II gives some resulting effects. Match the statements in Column I with the statements in Column II and indicate your answer by darkening appropriate bubbles in the 4 4 matrix given in the ORS.
Options
- AA-p, r; B-r; C-q; D-p, q
- BA-p; B-s; C-s; D-p, q
- CA-q; B-r, s; C-s; D-p, q, r
- DA-r, s; B-q; C-p; D-p, q, s
Correct answer
C. A-q; B-r, s; C-s; D-p, q, r
Step-by-step solution
- A (Cap connected to wire): Only thermal energy generated (q). - B (Wire moved in magnetic field): Constant potential difference ((r) ) and constant charges at ends ((s) ). - C (Wire in electric field): Constant charges at ends (s). - D (Battery connected): Constant current ((p) ), thermal energy ((q) ), constant potential difference ((r) ). Thus, ( A q , B r , s , C s , D p , q , r ), matching option (3).
