23. Two men have constructed a shed but now need to move it a short distance into
position.
They decide to push it across the garden.
They both push horizontally, with the same force, so that the shed moves at a slow
but constant speed.
Given there is a resistance of 540 N, what force does each man push with?

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
