JEE 2022 | समतल में गति - L6 | speed in plane | Hindi Medium | Ravikant Sir | 7PM

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

A car can cover a distance of 420 km in 7 hours. How much speed should be increased to cover this distance in 6 hours ? कोई कार 7 h में 420 km की दूरी तय कर सकती है | दूरी को 6 h में तय करने के लिए गति कितनी बढ़ानी होगी?

There of the fundamental constant of physics are the universal gravitational constant, G=6.7xx10^(-11) m^(3) kg^(-) s^(-2) , the speed of light c=3.0xx10^(8) m//s and Planck's constant, h=6.6xx10^(-34) Js^(-1) . two particles A and V are projected in the vertical plane with same initial velocity u_(0) fro part (0,0) and (l,-h) towards each other as shwon in figure The path of particle A with respect to particle B will be –
