NEET · Physics · STD 12 - 5. Magnetism and matter
A sheet is placed on a horizontal surface in front of a strong magnetic pole. A force is needed to: \(A\). hold the sheet there if it is magnetic. \(B\). hold the sheet there if it is non-magnetic. \(C\). move the sheet away from the pole with uniform velocity if it is conducting. \(D\). move the sheet away from the pole with uniform velocity if it is both, non-conducting and non-polar. Choose the correct statement(\(s\)) from the options given below:
- A \(A\) and \(C\) only
- B \(A\), \(C\) and \(D\) only
- C \(C\) only
- D \(B\) and \(D\) only
Answer & Solution
Correct Answer
(A) \(A\) and \(C\) only
Step-by-step Solution
Detailed explanation
\(A\). A magnetic pole will repel or attract magnetic sheet so force is need. \(B\). If sheet is non-magnetic, no force needed.
