Web8 apr. 2024 · Let a,b,c be three coplanar concurrent vectors such that angles between any two of them is same. If the product of their magnitudes is 14 and (a ×b)⋅(b ×c)+(b ×c)⋅(c ×a)+(c ×a)⋅(a ×b)=168, then ∣a ∣+∣b ∣+∣c ∣ is equal to: 10 14 (C) 16 (D) 18 Explanation ∣a ∣b ∣∣C ∣=14a ∧b =b ∧c =c ∧a =θ=32π. Viewed by ... WebSuppose the angle between vectors a and b is θ1 , between b and c is θ2 and between c and a is θ3. Given that a+b+c =0 a+b = -c Therefore (a+b).
