what happens when a charge
1- A electron with a speed of (3x10° m/s) moves into a uniform electric field of magnituc of (1 x 103 N/C). The field lines are parallel to the electrons velocity. How far does th travel before it brought to rest? (a) 2.56 cm(b) 5.12 cm (c) 11.2 em 1) 3.3-1 nm (e) 4.24 m 2- What happens when a charged insulator is placed near an uncharged metallic objeci? (a) They repel each other. (b) They auract each other. n the insulator is positive or negative. (d) They exert no electrosiatic force on each other. (c) The charged insulator always spontancously discharges 3 The magnitude of the eleciric force beween two protons is 2.30 × 10-2b N. How far apart are they? (a) 0.100 m (b) 0.022 0 m (c) 3.10 m (d) 0.005 70 m (e) 0.480 m 4 An object with negative charge is placed in a region of space where the eleciric field is directed vertically upward. What is the direction of the eleciric force exerted on this charge? (a) It is up. (b) It is down. (c) There is no force. (d) The force can be in an diExplanation / Answer
2. (d) they exeret no electrostatic force on each other
reason, unless both interacting body has some charge irrespective of sign , there won't be any electrostatic interaction between the bodies.
