- This time your object has a mass of 20.4 kg. Now imagine taking all the protons out of the object and stuffing them into a box. Also take all the electrons out of the object and stuff them in a second box. How much charge is contained in the box with all the protons? Question 2 options: 3.90E+09 C 4.89E+08 C 9.77E+08 C 1.95E+09 CTwo small balls with a mass of 2 g each are hanging on two separate strings 0.25 m (25 cm) long attached to a common point. They are given an identical negative charge and spread apart to a distance 3 cm from each other. Determine the charge on each ball by finding the forces in equilibrium and using Coulomb's law. How many electrons are there on each ball? What will happen in an identical situation if the mass of the balls is cut in half? What would happen if the charge on each ball is doubled?A mass of 6 X 10-24 kg has a charge of 2|e| where e is the charge on an electron. a) What is its KE at 2% of the speed of light? b) What is this in eV? c) What is the voltage needed to obtain this energy?
- A stationary block has a charge of +6.0 x 10^-4 C. A 0.80-kg cart with a charge of +4.0 x 10^ -4 C is initially at rest and separated by 4.0 m from the block. Calculate the cart’s speed after it is released and moves along a frictionless surface to a distance of 10.0 m from the block.3. Two small aluminium spheres weighing 10 g each are suspended by 10-cm-long silk threads from two hooks separated 10 cm apart. When the spheres are uncharged, the silk threads are vertical due to the gravitational pull of the earth (the effect of gravity between the two spheres is negligible). A fraction of the electrons from each sphere is then removed, leaving behind a net positive electric charge on each sphere. Once the spheres are charged, they move away from each other causing the thread to hang at 45 degrees from vertical. a) What is the net positive charge on each sphere? Hint: The horizontal and vertical forces acting on each sphere must be equal for the net force to be along a 45 degree angle. b) Given that the atomic mass of Aluminium is 27 and the atomic number is 13, what percentage of total electrons of the aluminium spheres need to be taken away to achieve this scenario?A mass of 8 X 10-24 kg has a charge of 4|e| where e is the charge on an electron. a) What is its KE at 4% of the speed of light? b) What is this in eV? c) What is the voltage needed to obtain this energy?
