Plane figures made of thin wires of resistance R = 50 milli ohm/metre are located in a uniform magnetic field perpendicular into the plane of the figures and which decrease at the rate dB/dt= 0.1 mT/s. Then currents in the inner and outer boundary are. (The inner radius a = 10 cm and outer radius b = 20 cm)

Question

Plane figures made of thin wires of resistance R = 50 milli ohm/metre are located in a uniform magnetic field  perpendicular into the plane  of the figures and which decrease at the rate dB/dt= 0.1 mT/s. Then currents in the inner and outer boundary are. (The inner radius a = 10 cm and outer radius b = 20 cm)

TuteeHUB · Answer

$$2\times {{10}^{-4}}\,A$$(clockwise),$${{10}^{-4}}\,A$$(anticlockwise)

TuteeHUB · Answer

$$2\times {{10}^{-4}}\,A$$(anticlockwise),$${{10}^{-4}}A$$(anticlockwise)

1.	Plane figures made of thin wires of resistance R = 50 milli ohm/metre are located in a uniform magnetic field perpendicular into the plane of the figures and which decrease at the rate dB/dt= 0.1 mT/s. Then currents in the inner and outer boundary are. (The inner radius a = 10 cm and outer radius b = 20 cm)
A.	\[{{10}^{-4}}A\](Clockwise), \[2\times {{10}^{-4}}\,A\](Clockwise)
B.	\[{{10}^{-4}}A\](Anticlockwise),\[2\times {{10}^{-4}}\,A\](Clockwise)
C.	\[2\times {{10}^{-4}}\,A\](clockwise),\[{{10}^{-4}}\,A\](anticlockwise)
D.	\[2\times {{10}^{-4}}\,A\](anticlockwise),\[{{10}^{-4}}A\](anticlockwise)
Answer» B. \[{{10}^{-4}}A\](Anticlockwise),\[2\times {{10}^{-4}}\,A\](Clockwise)
