Answer 1

at a distance The magnitude of an electric field (E) so frohm a point charge a E = Kemente E a Z2 / Q = Constant] E = 100 NIC, 7 = 12 mm E = 400 NIC, 8,=? Part -A ३ ३ or 8, = 12x P, = 6 mm Part-B E = 100 NIC 7 = 12 mm Ez = 16 NIC, Yz = ? - or to y = { ov, The 100 ot, Tz - Yex 10 - 72 = 30 mm
