(a) You pull a solid zinc ball with a density of 7.14 g/cm³ and a radius of 1.10 cm upward through a fluid at a constant speed of 7.00 cm/s. The fluid exerts a drag force that is directly proportional to speed, and the proportionality constant is 0.950 kg/s. What is the magnitude of the force (in N) you exert on the ball? (You may ignore the buoyant force.)

________N

(b)

What If? By what percentage would the upward force exerted on the zinc ball have to be increased for the speed of the ball in the fluid to increase to double its original value?

________%

A 200 g solid plastic ball (i.e., an insulator) with a 30 cm radius has a total charge of -20 μC that is uniformly distributed throughout its volume. The center of the ball is at the origin. A –5 μC point charge with a mass of 30 g is placed on the x-axis, 100 cm away from the center of the ball. Both charged objects are held in place. a) Find the electric field (magnitude and direction) at the following...

You have a glass ball with a radius of 2.00 mm and a density of 2500 kg/m3. You hold the ball so it is fully submerged, just below the surface, in a tall cylinder full of glycerin, and then release the ball from rest. Take the viscosity of glycerin to be 1.5 Pa s and the density of glycerin to be 1250 kg/m3. Use g = 10 N/kg = 10 m/s2. Also, note that the drag force on a ball...

The density of a 10 kg cube of silver is 10.5 g/cm3. What would the density of a 5 kg cube of silver be? I thought the answer would be 5.25 g/cm^3 because m1/m2=p1/p2 so 10kg/5kg=10.5 g/cm^3/ x and you solve for x. But this is coming up as wrong and I don't know why, do i need to convert the kg to g???
