Let L_1 be the line vec r_1=2 hat i+ hat j- hat k+lambda(i+2 hat k) and let L_2 be the line vec r_2=3 hat i+ hat j+mu(i+ hat j- hat k) . Let pi be the plane which contains the line L_1 and is parallel to L_2dot The distance of the plane pi from the origin is a. sqrt(6) b. 1//7 c. sqrt(2//7) d. none of these

Two transparent media A and B are separated by a plane boundary. The speed of light in medium A is 2.0xx10^(8)ms^(-1) and in medium B is 2.5xx10^(8)ms^(-1) . The critical angle for which a ray of light going from A to B suffers total internal reflection is
