00:00 - 00:59 | so that the vectors to ICAP - 2 J cap + K cap and ICAP - 2 J cap - 5 k cap are at right angles then this question we have to show that these two vectors are perpendicular to let a vector equal to two ICAP - 2 J cap + K cap and b vector equal to ICAP - 3 J cap - 5 KK now we know that If two vectors are perpendicular to each other then there is scalar product is equal to zero so we will find a vector dot b vector is equal to two ICAP - 2 J cap + K cap dot 3 J cap - 5 KK ok equal to 2 into 1 is to 3 minus 1 into X + 3 + 1 into minus 5 is -5 2 + 3 is 55 - 50 a vector and b vector is |

01:00 - 01:59 | equal to zero from where we get you can say that a vector is perpendicular to vector so given vectors are perpendicular to each other that is given at right angles this is the solution of the given question thank you |
