Chose the dipole with highest potential energy with respect to constant external electric field E pointing to the right a) b) c) d) e) 2. The Coulomb’s force between two charges at a given distance is F. When each charge is doubled and the distance is doubled, the force is a) 4F/9 b) 9F/4 c) 9F/16 d) F e) 3F/2 3 . The charge on the capacitor C (cf. diagram) is a) 10pC b) 4nC c) 4pC d) 2pC e) 6pC 4 . Two large, parallel plates, one charged to η 1 = 4.42 nC/m 2 and the other to η 2 = -4.42nC/m 2 are d= 1.0 cm apart. The potential difference between the plates is (in V) a) 1.0 b) 5.65 c) 4.52 d) 56.5 e) 0.56 5 On the diagram all three particles have the same mass and speed. The relation between their charges is a) q a > qb > qc b) qa> qb = qc c) qb > qc > qa d) qc > q b > qa e) qa = q b > qc 6 . In SI the unit for this combination
