Distance between charges is d=sqrt{3²+3²} =4.24 cm x=d/2 =4.24/2 =2.12 cm =0.0212 m E=kq₁/x²-kq₂/x² = =k12e/x²+k3e/x²=k9e/x²= =9•10⁹•15•1.6•10⁻¹⁹/0.0212²= =4.8•10⁻⁵ N/C try this !!!

any hint how i can solve this What is the magnitude of the net electrostatic force a Boron nucleus would experience at the point halfway between the Magnesium nucleus and the 3e charge on the y axis in N? ???

thank bro !!! but for b)is E(0.05) = k*1e-5/(0.05^2)=3.6e7 C

hai Unrickross 4th question ans is Distance between charges is d=sqrt{3²+3²} =4.24 cm x=d/2 =4.24/2 =2.12 cm =0.0212 m E=kq₁/x²-kq₂/x² = =k12e/x²+k3e/x²=k9e/x²= =9•10⁹•15•1.6•10⁻¹⁹/0.0212²= =4.8•10⁻⁵ N/C try this !!!

hai Unrickross !!! i need ans for 5th question ??? 5??

11 years ago

unrickross ! first tell me if u got green check on that 4th question better i have to explain !!! so what about 5th question ???

11 years ago

Oh God unrickross i made mistake on my sign but the last ans is correct so it would be Distance between charges is d=sqrt{3²+3²} =4.24 cm x=d/2 =4.24/2 =2.12 cm =0.0212 m E=kq₁/x²+kq₂/x² = =k12e/x²+k3e/x²=k15e/x²= =9•10⁹•15•1.6•10⁻¹⁹/0.0212²= =4.8•10⁻⁵ N/...
