NEET Physics Faraday's Law MCQ Question
Type: MCQ-numerical-Medium-Class 12
The flux linked with a circuit is given by ϕB = t² + 2. The graph between time (X⁻axis) and induced emf (Y⁻axis) will be a
A
straight line through the origin
B
straight line with positive intercept
C
straight line with negative intercept
D
parabola not through the origin
Correct Answer
Option 1
Detailed Explanation
The induced emf is the derivative of flux with respect to time. Differentiating ϕB = t² + 2 gives emf = 2t, which is a straight line through the origin.
