Q.3An electric field E = (20 i +30) N/C exists in the space. W the(207+30 7 N/C exists in the space. If the potential at the origin is taken to befind the potential at (2m, 2m).

Answer»

Given:→E=(→i20+→j30)N/CE→=(i→20+j→30)N/C→r=(2→i+2→j)r→=(2i→+2j→)So,V=−→E.→rV=-E→.r→⇒V=−(→i20+30→j).(2→i+2→j)⇒V=−(2×20+2×30)=−100V
