1. Two identical objects have charges of +51] pic and '10:; C. rEspectivel-f. When placed a distance d apart, their force of attraction is 2J1} N. If the objects are touched together. then moved to a distance of separation of 2d, what will he the new force between them? 2. A positive test charge, qt = +21] 3: l'g C, is placed in an electric field and experiences a force of F = 4.1:: at 1D'9H[w1. a] What is the electric eld intensity at the location of the test charge? h} Predict the force that would he experienced by a charge of q = +9D x 10'5 C if it replaced the test charges qt. 3. How mam; electrons must he removed from a spherical conductor with a radius of 4.8] cm in order to make the electric eld intensity just oUtsidE its surface 3.95 x 1'2]3 NEE
