Q1. Two point charges, q1= 2.00 nC and q2= -6.10 nC, are 0.100 m apart. Point A is midway between them; point B is 0.080 m from q1 and 0.060 m from q2 (see the attachment). Take the electric potential to be zero at infinity.
Find out the potential at point A.
Find out the potential at point B.
Find out the work completed by the electric field on a charge of 2.80 nC that travels from point B to point A.
Q2. A man pushes on a piano with mass 180 {rm kg} so that it slides at constant velocity down a ramp that is inclined at 20.0^circ above horizontal floor. Overlook any friction acting on the piano.
Car A uses tires for which the coefficient of static friction is 1.1 on a particular unbanked curve. The maximum speed at which the car can negotiate this curve is 25 m/s. Car B uses tires for which the coefficient of static friction is 0.65 on the s..
