TS EAMCET · Physics · Magnetic Effects of Current
Statement (I) : A uniform electric field and a uniform magnetic field are pointed in the same direction. If an electron is projected in the same direction the electron velocity will decrease in magnitude. Statement (II) : Two infinite long parallel wires are carrying current in the same direction. The magnetic field at a point midway between the wires is zero. Statement (III) : No net force acts on a rectangular coil carrying a steady current when suspended in a uniform magnetic field. Which of the following is correct?
- A Statements I, II and III are true.
- B Statements I and II are true, but statement III is false.
- C Statements II and III are true, but statement I is false.
- D Statements I and III are true, but statement II is false.
Answer & Solution
Correct Answer
(A) Statements I, II and III are true.
Step-by-step Solution
Detailed explanation
\(\overrightarrow{\mathrm{B}}\) will not effect electron and \(\overrightarrow{\mathrm{E}}\) will reduce electron velocity as electric field on it is in direction opposite to field. So (I) is correct…
