Two snowcats tow a housing unit to a new location at McMurdo Base, Antarctica, as shown in the figure. The sum of the forces and exerted on the unit by the horizontal cables is parallel to the line L, and N. Determine ? Determine the magnitude of ?
Two small charged objects repel each other with a force F whenseparated by a distance d. if the charge on each object is reducedto one-fourth of its original value and the distance between themis reduced to d/2, the force becomes:
Three identical blocks connected by ideal strings are being pulled along a horizontal frictionless surface by a horizontal force The magnitude of the tension in the string between blocks B and C is T=3.00N. Assume that each block has mass m=0.400kg.
What is the magnitude F of the force?
What is the tension in the string between block A and block B?
