A conductor OC shown in figure below of length 0.20 m lies at an angle 0 of 41 to a magnetic field of flux density 0.05 T. What is the force acting on the conductor when it carries a current of 355 mA. Question 21 1 pts Give your answer to 4 decimal places. A seedling of height 8 cm is placed 10 cm away from a convex lens. The focal length of the lens is 6 cm. What characteristics does the image have (image A B distance, magnification, image height)? Show you calculations. magnetic field The image distance is 15 cm, the image is real and enlarged with a magnification of lines C 1.5X. The image distance is 15 cm, the image is real and reduced with a magnification of 2.OX. O D The image distance is 15 cm, the image is real and enlarged with a magnification of 2.0X. The image distance is - 15 cm, it is imaginary and enlarged with a magnification of 1.5X. The image distance is 25 cm, the image is real and enlarged with a magnification of 1.5X. Question 20 1 pts Consider a point charge Q = +8.3 x 10" C. Does the charge have an excess or deficiency of electrons? Determine the number of electrons that the charge is either deficient of in excess of. Excess and about 5.2 x 1015 electrons. Excess and about 6.2 x 1015 electrons. O Deficiency and about 3.2 x 1019 electrons. O Deficiency and about 5.2 x 1015 electrons. O Deficiency and about 6.2 x 1015 electrons
