    there is this question that i came across:

    O is the origine .
    OA is i+3j
    OB is -2i+j
    P is a variable pt such that P lies on the line defined by AB

    find :
    1) the value of t such that vector OP is perpendicular to vect AB
    2)the value of t such that modulus of vector OP =modulus of vect AP

    Another question is that ,
    OA =7i+7j
    OB=3i+5j
    C is the foot of perpendicular from O to AB.
    FInd the position vector of C relative to O.

    Well, i got the answer for the 2nd question.
    but i am not sure if my methode is correct .
    the answer is -1.4i+2.8j
