Apoint charge q2 = -3.8 μc is fixed at the origin of a co-ordinate system as shown. another point charge q1 = 1.7 μc is is initially located at point p, a distance d1 = 8.5 cm from the origin along the x-axis
the charge q2 is now replaced by two charges q3 and q4 which each have a magnitude of -1.9 μc, half of that of q2. the charges are located a distance a = 2 cm from the oringin along the y-axis as shown. what is δpe, the change in potential energy now if charge q1 is moved from point p to point r?

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 710 n/m. it is initially at rest on an inclined plane that is at an angle of θ = 23° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.19. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. a) what is the block's initial mechanical energy? b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
