Two monkeys of masses 10 kg and  8 kg are moving along a vertical rope as shown in diagram. The former climbing up with an acceleration of  $2 \text{m}/{\text{s}}^2$, while the later coming up with a uniform velocity of 2 m/s. Find the tension in the rope at the fixed support.(in SI units) (take  $g=9.8m/{\sec }^2$)
