Two identical small metal spheres with q1 > 0 and |q1| > |q2| attract each other with a force of magnitude 77.9 mN when separated by a distance of 1.79 m . Now the spheres repel each other with a force of magnitude 7.79 mN. What is the final charge on the sphere on the right?

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

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
