A charged cloud system produces an electric field in the air near the earth's surface. A particle of charge16.2×10−19C is acted on by a downward electrostaticforce of 3×10−6N when placed in this field. The gravitational and electrostatic force, respectively,exerted on a proton placed in this field are(1) 1.64×10−26N , 2.4×10−16N (2) 1.64×10−26N, 2.9×10−16N (3) 1.56×10−18N, 2.4×10−16N (4)2.9×10−17N ,1.64×10−26N |
