A) \[\frac{\varepsilon {{\ell }^{2}}B}{\rho }\]
B) \[B{{\varepsilon }_{0}}K{{\ell }^{2}}\varepsilon \]
C) \[\frac{\varepsilon {{\ell }^{2}}B}{K\rho }\]
D) \[B{{\varepsilon }_{0}}{{\ell }^{2}}\varepsilon \]
Correct Answer: D
Solution :
[d] Impulse \[=\int{idB}\,\,(dt)\] \[dB\Delta q=\frac{dB{{\varepsilon }_{0}}{{\ell }^{2}}\varepsilon }{d}=B{{\varepsilon }_{0}}{{\ell }^{2}}\varepsilon \]You need to login to perform this action.
