This is a separable differential equation.
To solve it:
1. Rearrange the equation to separate variables.
2. Integrate both sides.
3. Use the initial condition \( y(0) = 5 \) to find the constant of integration.
4. Solve for \( y(n2) \). After performing the integration, you can find the value of \( y(n2) \).
A conducting bar moves on two conducting rails as shown in the figure. A constant magnetic field \( B \) exists into the page. The bar starts to move from the vertex at time \( t = 0 \) with a constant velocity. If the induced EMF is \( E \propto t^n \), then the value of \( n \) is _____.
