Answer 1

Ei Q1 d = 12cm a Р E. The Electric field intensity at Point due to Charge a, is IQ,1 by magnitude 476. x2 the direction is toward night. the magnitude ude of Electric field due to Charge Q₂ is E 1021 which is Ante+d)? directed toward right to left. .& 2 if they Cancels each other, then, E, E2 3 IQ, I IQql 4 TE.x2 2 Ant.

> ntd -I lol IQ11 I . 1 Q2). \Q11 T FIR = ) de = -1 lau \Q11 since; a a is the distance (which can't be negative, si, IQil where 2 aa c- t TQ11 poot we will take the t've so gle -1 + IQ21 TQI d ra TA IQ) - Qil given, Q = -39 me 7 19 11=39ne e Q₂ = 48 mc | Q₂l = 48 m d h = ola 48 39 -1 since; d = 12cm = 12x102 m
