As shown below, two blocks of equal mass m are attached to a string that is part of a pulley system. One block is on a flat, horizontal surface while the other is on a surface inclined at an angle of 45°. If no friction is acting upon the system, the magnitude of the acceleration of the system is _.

radiation warms things up temp rises convection currents air circ windy weather

the force on the thing and the distance the force moves the thing

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
