In fig. 1 below, MN is a light uniform metre rule pivoted at 0, the 80cm mark. A load of mass 3.0kg is suspended on the, rule at L, the 1.0cm mark. If the rule is kept in equilibrium by a string p, fixed at p and attached to the rule at R, the 20cm mark, then the tension T in the string is:

(a) 25N

(b) 50N

(c) 250N

(d) 5000N

(e) 25000N
