Qn 14 

Paragraph for Question Nos. 13 and 14 A particle is suspended by three equal strings, of length a, from three points forming an equilateral triangle of side 2b, in the horizontal plane. 13. The tension in the string will be 3mga mga (A) V3(3a – 4b°) (B) V3(3a? – 4b°) (C) 3mga mga V(4a* – 3b*) (D) V(4a? – 3b°) If one string be cut, the tension of each of the other two strings will be changed in the ratio (i.e. the ratio of final tension after cutting the string to tension before cutting the string): За? - 4b2 (A) 2(a? -b?) 14. 4а? - 3b? (В) 2(a? - b?) 15/34 3a? – 4b? (C) (a² – b?) 4a? - 3b? (D) (a? – b?)
