Formula OF R || r || r1 r2 and r3 with ProOF

The possible percentage error in computing the parallel resistance R of three resistances 1/R=(1)/R_1+ 1/R_2 1/R_3 from the formula , if R_1, R_2, R_3 are each in error by plus 1.2% is :

For any three non-zero vectors r_1,r_2 and r_3 .|(r_1.r_1,r_1.r_2,r_1.r_3),(r_2.r_1,r_2.r_2,r_2.r_3),(r_3.r_1,r_3.r_2,r_3.r_3)|=0. Then which of the following is false

There circle C_1,C_2 and C_3 with radii r_1 , r_2 and r_3 (where r_1 तीन वृत्त C_1,C_2 तथा C_3 जिनको त्रिज्याएँ r_1 , r_2 तथा r_3 है, (जहाँ r_1

Figure shows three resistor configurations R1,R2 and R3 connected to 3 V battery . If the powers dissipated by the configuration R1,R2 and R3 are P1,P2 and P3, respectively, then

Let omega be a cube of unity . If r_1,r_2,and r_3 be the numbers obtained on the die. Then probability of omega^(r_1)+omega^(r_2)+omega^(r_3)=0 is
