A charged cloud system produces an electric fiein the air near the earth's surface. A particle of change-2 10-° C is acted on by a downward electrostaticforce of 3 x 10-6 N when placed in this field. Thegravitational and electrostatic force, respectivelyexerted on a proton placed in this field are(1) 1.64 x 10-26 N. 24 * 10-16 N(2) 164 x 10-26 N. 1.5 x 10' N(3) 1.56 * 10-18 N. 2.4 x 10-16 N(4) 1.5 * 10' N, 2.4 x 10-16 N |
