Answer: higher and lower
Explanation:
charge in an electric field will experience a force in the direction of decreasing potential energy. Since the electric potential energy of a negative charge is equal to the charge times the electric potential the direction of decreasing electric potential energy is the direction of increasing electric potential.
The pressure at the bottom of a column of fluid in a container
depends only on the depth of the fluid, not on the shape of the
container. The pressure is simply the result of the weight of the
fluid resting on the bottom.
Answer:
B = 1.823 T.
Explanation:
Given,
Number of turns,N = 170 turn
Side of square loop,L = 22 cm
Maximum torque, τ = 295 N.m
Current on the loop, I = 20 A
Magnetic strength = ?
Torque = N BIA
300 = 170 x B x 20 x 0.22²
300 = 164.56 B
B = 1.823 T.
Hence, the magnetic field strength is equal to B = 1.823 T.
