4. Solve the problem: An op-amp astable multivibrator circuit is constructed (as shown on figure 3) using the following components. \( \mathrm{R} 1=35 \mathrm{k} \Omega, \mathrm{R} 2=30 \mathrm{k} \Omega, \mathrm{R}=50 \mathrm{k} \Omega \) and \( \mathrm{C}=0.01 \mathrm{uF} \). Calculate the circuits frequency of oscillation.
