49. Horizontal conductor 100 g and a length of 0.5 m is on an inclined plane at an angle of 30 degrees with the horizontal, perpendicular to the horizontal magnetic field with an induction of 0.1 tesla. What is the minimum force must be applied to the conductor in parallel incline to keep it at rest, if the current in the conductor 10 A? The coefficient of friction of 0.1.
