The potential energy of a particle varies with distance x from a fixed origin as 
where A and B are dimensional constants, then the dimensional formula for AB is
Two springs of spring constant 1500 N/m and 3000 N/m respectively are stretched with the same force. They will have the potential energy in ratio
A body is placed on a table which is kept on the ground. The potential energy of the body
The potential energy stored in a spring of spring constant 25 Nm–1 when stretched by 1 cm is
A simple pendulum of mass m and length l swings back and forth upto an angle of 60° with vertical. The potential energy at the highest point (assume potential energy at lowest position to be zero)
