Below is a diagram of the forces acting on a 100 gram ball that is placed on a horizontal frictionless surface. All the forces are parallel to the surface. F1 has a magnitude of 2 N, F2 has a magnitude of 3 N, and F1 and F2 are perpendicular to one another. Please, find the magnitude of force F3 if the ball has acceleration of 0.2 m/s2 in the direction of F1 force.

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?
