A 1 ~N pendulum bob is held at an angle from the vertical by a 2 ~N horizontal force F as shown in the figure. The tension in the string supporting the pendulum bob (in newton) is

Step-by-step solution

As the bob is in equilibrium under the effect of three forces -T, F and W T + P + W =0 From Eqs. (i) and (ii) T^2=W^2+F^2 or aligned T & = W^2+F^2 & = (1)^2+(2)^2 & = 5 aligned
