An infinite sheet of charge that has a surface charge density of 36 nC/m2 lies in the yz plane, passes through the origin, and is at a potential of 1.5 kV . A long wire having a linear charge density of 57 nC/m lies parallel to the y axis and intersects the x axis at (4.1 m, 0, 0). What is the potential energy of a 2.4 nC charge placed at (2.3 m, 0, 0) ? The value of the permittivity

Astone is thrown with a speed v0 and returns to earth, as the drawing shows. ignore friction and air resistance, and consider the initial and final locations of the stone. which one of the following correctly describes the change δpe in the gravitational potential energy and the change δke in the kinetic energy of the stone as it moves from its initial to its final location? options a.δpe = 0 j and δke = 0 j b.δpe is positive and δke is negative c.δpe = 0 j and δke is positive d.δpe is negative and δke is positive e.δpe = 0 j and δke is negative
