Best ResponseYou've already chosen the best response.1it's not the right answer

Best ResponseYou've already chosen the best response.1it is not easy. it is a vector quantity. therefore you must have to consider directions.

Best ResponseYou've already chosen the best response.1hello. it is taking too much time for me. lets solve step by step here. ok. force of +15nC will be represented by F15 force of 10nC will be represented by F10 force of 5nC will be represented by F5 ok.

Shayaan_Mustafa

Best ResponseYou've already chosen the best response.1now as you can see. on 10nC there are two forces acting on it. 1)F15 which is attractive and at an angle of 45 2)F5 which repulsive.

Best ResponseYou've already chosen the best response.1F15 can be resolve into factors. along xaxis and along yaxis.

Shayaan_Mustafa

Best ResponseYou've already chosen the best response.1forces along yaxis can be calculated as, F15y=(kq1q2)/r² sin45 and F5y=(kq1q2)/r² forces along xaxis can be calculated as, F15x=(kq1q2)/r² cos45

Best ResponseYou've already chosen the best response.1well you still have to add the F5 on F10 don't you? which will only consist of y direction force

Best ResponseYou've already chosen the best response.1well you still have to add the F5 on F10 don't you? which will only consist of y direction force on yaxis: F10y=F15sin45  F5 on xaxis: F10x= F15x finally, \[F _{10}=\sqrt{(F _{10y})^{2}+(F _{10x})^{2}}\] This is complete.

Best ResponseYou've already chosen the best response.1ok w8. let me analyze.

Best ResponseYou've already chosen the best response.1The three vectors above form the triangle AOB. using Law of Cosines , \[ab^{2}=a^{2}+b^{2}2ab\cos \theta\] using properties of dot product. \[ab^{2}=(ab).(ab)\] \[=a.aa.bb.a+b.b\] \[=a^{2}+b^{2}2a.b\] original becomes, \[ab^{2}=a^{2}+b ^{2}2ab\cos \theta\] and, \[a^{2}2a.b+b^{2}=a^{2}+b ^{2}2ab\cos \theta\] now cancel terms which are same and you will got \[a.b=ab\cos \theta\]

Best ResponseYou've already chosen the best response.3Just skimming through this.... You should recognize that the angle is not 45 degrees because it's a rectangle, not a square, so the values above would not yield the correct answer.

Best ResponseYou've already chosen the best response.1good point, i wasn't using 45 though, just used the measurements given. i still need to resolve, haven't got to it yet

Shayaan_Mustafa

Best ResponseYou've already chosen the best response.1oh yes. so angle is not 45degree. it can be calculated as, \[\tan^{1} (0.01/0.03)=18.43degrees.\] Kindly use this angle instead of 45.

Best ResponseYou've already chosen the best response.3elica I assume you are adding the components separately and then using the Pythagorean Theorem to calculate the magnitude of the resultant, right?

Best ResponseYou've already chosen the best response.1thank you everyone, i did get the right answer finally. i was confused about +/. i thought the  charge on negative would make it negative direction going down y, making it double negative...so i was just getting calculations wrong. it was 18 degrees ^^
