In the arrangement shown in figure \(a_1,a_2,a_3\text{ and } a_4\) are the accelerations of masses \(m_1,m_2,m_3\text{ and }m_4\) respectively. Which of the following relation is true for this arrangement?
1. \(4 a_1+2 a_2+a_3+a_4=0 \)
2. \(a_1+4 a_2+3 a_3+a_4=0 \)
3. \( \mathrm{a}_1+4 \mathrm{a}_2+3 \mathrm{a}_3+2 \mathrm{a}_4=0 \)
4. \( 2 a_1+2 a_2+3 a_3+a_4=0\)
1. \(4 a_1+2 a_2+a_3+a_4=0 \)
2. \(a_1+4 a_2+3 a_3+a_4=0 \)
3. \( \mathrm{a}_1+4 \mathrm{a}_2+3 \mathrm{a}_3+2 \mathrm{a}_4=0 \)
4. \( 2 a_1+2 a_2+3 a_3+a_4=0\)
