Question

Two metal plates are separated by 2 cm. The potentials of the plates are -10 V and + 30 V. The electric field between the two plates is ______.

विकल्प

• 2000 V/m

• 500 V/m

• 3000 V/m

• 1000 V/m

Answer 1

Two metal plates are separated by 2 cm. The potentials of the plates are -10 V and + 30 V. The electric field between the two plates is 2000 V/m.

Explanation:

E = `"V"/"d" = (30-(-10))/(2 xx 10^-2) = 2000  "Vm"^-1`
