0.9 + 0.99 + 0.999 + ……. up to 51 terms = 51 - (1)/(p)(1-(1))/(10^(q)) where p, q in N then find the value (p + q)/(15) .

A thin prism P of refracting angle 3^(@) and refractive index . 1.5 is combined with another thin prism Q of refractive index 1.6 to produce dispersion without deviation. Then the angle of prism Q is

Charges q_(1) = 1.5 mC, q_(2) = 0.2 mC and q_(3) = -0.5 mC , are placed at points A,B,C respectively as shown in Fig. If r_(1) = 1.2m and r_(2) = 0.6m , calculatae magnitude of resultant force on q_(2) .
