A positive point charge

q1 = +5.00×10−4 C is held at a fixed position. A small object with mass 4.00×10−3 kg and charge q2 = −5.00×10−4 C is projected directly at q1. Ignore gravity. When q2 is 0.400 m away, its speed is 800 m/s.

What is its speed when it is 0.200 m from q1?

Express your answer with the appropriate units.

A small metal sphere, carrying a net charge of q1= -3.10 micro C is held in a stationary position by insulating supports. A second small metal sphere, with a net charge of q2= -7.90 micro C and mass 1.90g is projected toward q1. When the two spheres are 0.800m apart, q2 is moving toward q1 with speed 22.0m/s. Assume the two spheres can be treated as point charges. You can ignore the force of gravity. A. What is the speed...

A point charge q1=5.00μC is held fixed in space. From a horizontal distance of 6.00 cm, a small sphere with mass 4.00×10^−3kg and charge q2=+2.00μC is fired toward the fixed charge with an initial speed of 41.0 m/s. Gravity can be neglected. Part A What is the acceleration of the sphere at the instant when its speed is 26.0 m/s?

A)Question based on content covered on Tuesday. A particle of mass 10-4 kg and charge q1 = 1.0 µC is shot at a speed of 10 m/s directly towards another particle q2 = 1µC that is held fixed. The initial distance between the two particles is 1.5 m, and your goal is to figure out how close q1 gets to q2. We will do that in several steps. What types of initial and final energy are present in the system...

A very small object with mass 8.30×10−9 kg and positive charge 7.00×10−9 C is projected directly toward a very large insulating sheet of positive charge that has uniform surface charge density 5.90×10−8C/m2. The object is initially 0.460 m from the sheet. A. What initial speed must the object have in order for its closest distance of approach to the sheet to be 0.230 m ? Express your answer to three significant figures and include the appropriate units.
