Since the resultant E is along -y axis therefore the sign of q1 and sign of q2 is negative in nature.
The detailed explanation is shown in following pages.
The net E is in negative y axis and the magnitude is 15.273 kN/C.
A 12.0 kg block of metal measuring 12.0 cm by 10.0 cm by 10.0 cm is suspended from a scale and immersed in water as shown in the figure below. The 12.0 cm dimension is vertical, and the top of the block is 6.00 cm below the surface of the water. (a) What are the magnitudes of the forces (in N) acting on the top and on the bottom of the block due to the surrounding water? (Use P. =...
A 18.5 kg block of metal measuring 12.0 cm by 10.0 cm by 10.0 cm is suspended from a scale and immersed in water as shown in the figure below. The 12.0 cm dimension is vertical, and the top of the block is 4.95 cm below the surface of the water. (a) What are the magnitudes of the forces (in N) acting on the top and on the bottom of the block due to the surrounding water? (Use P. -...
A flat rectangular surface 12.0 cm by 22.0 cm is at 30° angle to a 0.850 T magnetic field. (the given angle is between the surface and the field lines.) find the magnetic flux through the surface.
A 4.0 cm tall object is placed 12.0 cm in front of a diverging lens. When the image of the object is measured it is found to measure 1.3 cm in height. What is the focal length of the lens? Draw a ray diagram with the object, image and focal points labeled.
A 18.5 kg block of metal measuring 12.0 cm by 10.0 cm by 10.0 cm is suspended from a scale and immersed in water as shown in the figure below. The 12.0 cm dimension is vertical, and the top of the block is 4.55 cm below the surface of the water. Figure (a) shows a vertical spring scale. The top of the scale has a hook attached to the ceiling. The bottom of the scale has a hook attached to...

The electric field 12.0 cm from the surface of a copper ball of radius 9.0 cm is directed toward the ball's center and has magnitude 3.0 ✕ 102 N/C. How much charge is on the surface of the ball (in C)? (Include the sign of the value in your answer.)
A diverging lens has a focal length of ?12.0 cm. Real or virtual choices = real or virtual Orientation= upright or inverted Relative Size= D(diminished) or E(enlarged) Find the image distance for objects placed these distances from the lens: 2.00 cm, 8.00 cm, 13.0 cm, 16.0 cm, and 17.0 cm. In each case, describe the image as real or virtual, upright or inverted, and enlarged or diminished in size (select E for enlarged or D for diminished). Part 1 out...
