363337 Three blocks \({m_{1}, m_{2}}\), and \({m_{3}}\) of masses \({1.5 {~kg}, 2.0 {~kg}}\), and \(10\,kg,\) respectively, are placed on a rough surface \({(\mu=0.20)}\), as shown in the figure. If a force \({F}\) is applied to give blocks an acceleration of \({3.0 {~m} / {s}^{2}}\), then the force that the \(1.50\,kg\) block exerts on the \(2.0\,kg\) block will be approximately
