Q. The force exerted to pull a cart is directly proportional to the acceleration produced in the body. Express the statement as linear equation in two variables and draw the graph of the same by taking the constant mass equal to 6 kg. Read from the graph, the force required when the acceleration produced is (i) $5$ $m/se{c}^2$ , (ii) $6$ $m/se{c}^2$
