41. Figure 7 below shows how the electric potential varies with distance in a certain region of space. From the graph above, it can be concluded that: 35 25 12 15 18 1 /em 1 The magnitude of the electric field in the region described has a uniform magnitude of 3.33 x 10 NC. 2 The electric potential in the region increases by equal amounts in equal time intervals. 3 The area under the graph is equal to electrostatic force on unit electric charge in the region. 42. Which of the following clearly distinguish(es) between magnetic fields and gravitational fields? Magnetic fields 1 Their effects can be shielded Gravitational fields Shielding is impossible All gravitational forces are attractive 2 They give rise to attractive or renulsive
