 1.an elastic string has lenght a when tension in it is 4N.its lenght is b when tension is 5N.what will be the length if it is subjected to tension of 9N a.a+b b.ba c.5b4a d.(a+b)/(ab)
2.two blocks of mass m and M are connected to each other thru a horizontal spring.if we push the mass m wid horizontal force F which causes acceleration A in mass m ,then accleration of M will be a.F/M b.F/(m+M) c.A d.(FmA)/M
