question 141

Multiple Choice

A circular conducting loop with a radius of $0.50 \mathrm {~m}$ and a small gap filled with a $10.0 - \Omega$ resistor is oriented in the $x y \text {-plane. }$ If a uniform magnetic field of $1.0 \mathrm {~T}$ making an angle of $30 ^ { \circ }$ with the $z \text {-axis, }$ increases to $10.0 \mathrm {~T} ,$ in $4.0 \mathrm {~s} ,$ what is the magnitude of the current that will be caused to flow in the loop if it has negligible resistance?

• A)0.01530393 A
• B)0.08835729 A
• C)0.15303932 A
• D)0 A
