" 31."2.bar(357)=?

The value of 2.bar(357) , is

The value of 2.bar(357) , is

Express 0.bar(13)+2.bar(31) as a rational number

The rational number which equals the number bar(2. 357) with recurring decimal is a. (2355)/(1001) b. (2379)/(997) c. (2355)/(999) d. none of these

If bar(a)=(3,1,-2) and bar(b)=(1,3,-2) then (bar(a)" "^(hat)bar(b)) = …………

Three charged particles are arranged in a line,as shown in figure.Calculate the net electrostatic force on particle3 ( the -4.0 muC on the right ) due to the other two charges. Strategy : The net force exerted on 3by particle 1 is the resultant of the force bar(F_(31)) exerted on 3 by particle 1 and the force bar(F_(32)) exerted on 3 by particle 2, bar(F) =bar(F)_(31)+bar(F)_(32)

If |bar(a)|=|bar(b)|=|bar(c)|=2 and bar(a).bar(b)=bar(b).bar(c)=bar(c).bar(a)=2 then [bar(a) bar(b) bar(c)] equal to

bar(b)=bar(i)-2bar(j)-3bar(k),bar(b)=2bar(i)+bar(j)-bar(k),bar(c)=bar(i)+ 3bar(j)-2bar(k) then bar(a).(bar(b)xxbar(c))
