0 votes 1 answer What is the angle between P and the resultant of (P Q) and (P Q) ? Magnitude Sum of Two vectors Vector P and Vector q is given by r^2 =p^2q^22pqcos($) _____(i) here $ indicates angle between them We are given r=pq so Squaring both the sides we get r^2=p^2q^22pq _____(ii) From (i) and (ii) we can write p^2q^22pqcos($)=p^2q^22pq therefore 2pq=2pqcos($)That is AB → =p, BC → =q ⇒ AC → =pq This definition of vector addition is referred to as the triangle law of addition You can then subtract vectors, for a−b simply means a−()b For example AB → =BC → −AC → As an example, consider the displacement

Explanation The form of a modus tollens argument resembles a syllogism, with two premises and a conclusion If P, then Q Not Q Therefore, not P The first premise is a conditional ("ifthen") claim, such as P implies QThe second premise is an assertion that Q, the consequent of the conditional claim, is not the case From these two premises it can be logically concluded that P,The locus of \(P\) will be the line \(x = a\), while the locus of \(Q\) will be \(x = a\) These are parallel straight lines These are parallel straight lines The diagram shows the case \(a = 2\)Subtracting a vector is the same as adding its negative The difference of the vectors p and q is the sum of p and –q p – q = p (–q) Example Subtract the vector v from the vector u Solution u – v = u (–v) Change the direction of vector v to get the vector –v
