Answer:
Answer:
Step-by-step explanation:
Let M is zero vector .
Q is middle in NO
so, Q is vector ( M + O)/2
E is the middle point of MQ.
so, E is vector {M+ O }/4
eqn of MO :
r = (1 - s) 0 + sO _________(1)
where s is constant.
r = sO
again, eqn of QE
r = (1 -t) Q +t (M+ O)/4_____(2)
where t is constant
solve eqns (1) and (2)
t = 4/3 and s = 1/3
hence, eqn of MO :
r = 1/3 O________(3)
now, eqn of MO from section formula ,
r = ß O /(ß + 1)______(4)
compare (3) and (4)
ß /(ß + 1) = 1/3
ß = 1/2
hence,
MR/MO = 1/3
MR/30 = 1/3
MR = 10 cm
