  2. BThe B - H curve for a ferromagnet is shown in the figure. The ferromagnet is placed inside a long solenoid with
  3. CThe B - H curve for a ferromagnet is shown in the figure. The ferromagnet is placed inside a long solenoid with
  4. DThe B - H curve for a ferromagnet is shown in the figure. The ferromagnet is placed inside a long solenoid with

Correct answer

C. The B - H curve for a ferromagnet is shown in the figure. The ferromagnet is placed inside a long solenoid with

Step-by-step solution

v=−(v0x0)x+v0v = - \left(\dfrac{{v}_{0}}{{x}_{0}}\right)x + {v}_{0}

a=vdvdxa = \dfrac{vdv}{dx}

a=[−(v0x0)x+v0][−v0x0]a = \left[- \left(\dfrac{{v}_{0}}{{x}_{0}}\right)x + {v}_{0}\right]\left[- \dfrac{{v}_{0}}{{x}_{0}}\right]

a=(v0x0)2X−v02x0a = {\left(\dfrac{{v}_{0}}{{x}_{0}}\right)}^{2}X - {v}_{0}^{2}{x}_{0}
